UGC NET Questions (Paper – 1)

Each group is a block of four consecutive letters written in reverse order. The starting letters Z, X, V and T occupy positions 26, 24, 22 and 20, decreasing by two each time. The next starting position is 18, which is R, and the reversed block from R through O is RQPO. Thus RQPO continues both the backward step and the internal reverse structure.

Option A:
Option A, RSTU, is in forward order and does not follow the reversal rule.

Option B:
Option B, RQOP, is not a clean reverse of four consecutive letters (the last two letters are out of order).

Option C:
Option C, SRQP, starts at S instead of R, breaking the −2 start-step rule and also distorts the block.

Option D:
Option D is correct because it starts at R (two positions before T) and lists R, Q, P, O in strict descending consecutive order.

Each term is 5 consecutive letters in reverse. Starting letters E(5), J(10), O(15), T(20) increase by +5. Next start is Y(25), giving YXWVU.

Option A:
Option A is correct because it starts at Y (+5 from T) and lists Y,X,W,V,U in reverse order.

Option B:
Option B starts at Z (+6 from T), breaking the +5 rule.

Option C:
Option C starts at W, not Y, and breaks the starting-letter progression.

Option D:
Option D repeats the last term.

Each term is a block of three consecutive letters arranged in reverse order, and the starting letters move backward by one. ZYX uses 26 to 24, YXW uses 25 to 23, XWV uses 24 to 22 and WVU uses 23 to 21. The next starting letter is V at position 22 moving back to U and T, so the reversed block is VUT. Thus VUT maintains both the backward shift in the starting letter and the internal reverse order.

Option A:
Option A is correct because it starts at V, exactly one position before W, and lists the next two letters U and T in descending order. This matches the pattern of overlapping reversed triples and keeps the shift of the starting letter constant. It also ensures that all letters inside the group are consecutive in reverse alphabetical order.

Option B:
Option B, UTS, reverses the internal positions differently and does not use V, which should be the starting letter according to the pattern. It also disrupts the way the groups overlap with their neighbours. Since it does not follow the same mechanism of backward stepping, UTS is not the correct continuation.

Option C:
Option C, TSV, rearranges the letters and fails to present a clean three letter consecutive block in reverse order. It also does not arise from shifting the starting letter back by one from W. Because it breaks both the structural and positional rules, TSV is inconsistent with the series.

Option D:
Option D, YZW, introduces letters that are not consecutive in the correct reversed manner following WVU. It also moves back to Y instead of correctly progressing to V. As a result, YZW does not align with the established pattern.

Each group is a block of three consecutive letters written in reverse order: ZYX (26–24), WVU (23–21), TSR (20–18) and QPO (17–15). The starting letters move backward by 3 positions: Z, W, T, Q. The next starting letter is N (14), and the reversed block from 14–12 is NML. Thus NML continues both the block size and the backward progression.

Option A:
Option A, ONM, uses the same letters but in a different arrangement. It begins with O (15), not N (14), breaking the backward step of 3 from Q. Therefore ONM does not satisfy the starting-letter rule.

Option B:
Option B, MNO, lists the letters in forward order rather than reverse. The pattern clearly uses descending triples. As it reverses the direction within each block, MNO cannot be the correct continuation.

Option C:
Option C is correct because it starts at N, which is exactly 3 positions before Q, and presents the triple in descending order N, M, L. This mirrors the structure of the previous groups and adheres to the same step size in the starting letters.

Option D:
Option D, KJI, begins too far back and uses a starting letter K that is 7 positions before Q. This does not match the consistent spacing seen between earlier groups. Hence KJI is not compatible with the pattern.

The groups descend in blocks of three letters: XYZ (24–26), UVW (21–23), RST (18–20) and OPQ (15–17). Each starting letter reduces by 3 positions (24, 21, 18, 15). The next starting position should be 12, corresponding to L, and the next block is LMN (12–14). Hence LMN is the only group that continues the pattern of moving each block three letters earlier in the alphabet.

Option A:
Option A, LMN, is correct because it begins at L, which is 3 letters before O, and forms the next three-letter block in descending order. It respects the length of the groups and the step size of −3 for the starting letter. This makes LMN a perfect fit for the series.

Option B:
Option B, KLM, starts too early at K, corresponding to a step of −4 from O, not −3. This over-adjustment does not match the observed behaviour of the series. As such, KLM cannot be considered correct.

Option C:
Option C, NOP, reverses the direction by moving forward after OPQ instead of backward. It also overlaps with OPQ by reusing O and P in a way that contradicts the blockwise descent. Therefore NOP does not align with the series rule.

Option D:
Option D, MNO, starts at M, which is 2 letters before O, not 3 letters before O. It breaks the fixed interval between the initial letters of successive blocks. Because it ignores the −3 step pattern, MNO is not a valid continuation.

Each term is 4 consecutive letters in reverse. Starting letters Z(26), V(22), R(18), N(14) decrease by −4. Next start is J(10), so the reversed block is JIHG.

Option A:
Option A is correct because J is −4 from N and J,I,H,G are consecutive in reverse order.

Option B:
Option B starts at K (11), which is −3 from N, not −4.

Option C:
Option C starts at M (13), which is −1 from N, not −4.

Option D:
Option D moves forward to P and breaks the backward step rule.

Each term is a block of four consecutive letters written in reverse order, and the starting letter moves forward by four positions each time. The starting letters D, H, L and P have positions 4, 8, 12 and 16, all increasing by 4. The next starting letter is position 20, which is T, and writing the four letter block from T in reverse gives TSRQ. This preserves both the plus four progression and the internal reverse arrangement.

Option A:
Option A, RQPO, rearranges letters including P and O but does not start with the correct letter T. It also breaks the strict descending order that characterises each block. Since it fails to follow the formula for the starting position and the internal structure, RQPO is not consistent with the pattern.

Option B:
Option B, SRQP, begins with S instead of T, which is only three positions ahead of P, not four. This changes the size of the jump in starting letters and disrupts the regularity of the sequence. Additionally, the letter order within the block does not correspond to a straightforward reverse of four consecutive letters starting at T.

Option C:
Option C, QPON, reverses the internal order of letters found around P but again starts with Q, not T, and does not reflect the plus four movement. It also returns to letters that are two positions behind P, which contradicts the forward movement of starting positions. Because it fails on both structural and positional grounds, QPON is not the correct continuation.

Option D:
Option D is correct because T is four positions after P and TSRQ lists T, S, R and Q as consecutive letters in descending order. It exactly mirrors the format of earlier blocks, which all reverse a run of four consecutive letters. This consistent adherence to both the starting letter progression and the reverse order makes TSRQ the valid next term.
