UGC NET Questions (Paper – 1)

The three-letter groups are formed from even-position letters of the alphabet: BDF uses (2, 4, 6), DFH uses (4, 6, 8), FHJ uses (6, 8, 10) and HJL uses (8, 10, 12). The starting positions of the groups are 2, 4, 6 and 8, increasing by 2. The next group should use (10, 12, 14), which correspond to J, L and N, giving JLN.

Option A:
Option A, ILN, begins at position 9 instead of 10, shifting the group off the even-position pattern. It also does not align with the established sequence of starting positions. Because the structure is based on even-numbered indices, ILN cannot be correct.

Option B:
Option B, JLN, is correct because it follows the pattern of moving the starting position forward by 2 and taking every second letter from there. It uses positions 10, 12 and 14, exactly as the rule demands. This preserves both the spacing and the parity of the positions.

Option C:
Option C, KMN, changes the distances between letters and alters the parity of the underlying positions. It does not result from the simple shift in the even sequence used in earlier terms. As such, KMN cannot be accepted as a valid continuation.

Option D:
Option D, HJM, repeats letters and fails to maintain the constant spacing of two positions between successive letters. It also does not continue the progression of starting positions properly. Therefore HJM does not satisfy the design of the series.

In AHO, BIP, CJQ and DKR the positions of the letters show the same wide gap between successive letters within each group. At the same time, each column increases by one letter from group to group: the first letters go A, B, C, D and the second letters H, I, J, K and the third letters O, P, Q, R. Extending these sequences gives E as the next first letter, L as the next second letter and S as the next third letter. This produces ELS, which alone satisfies both the internal spacing and the column wise progressions, making it the correct continuation.

Option A:
Option A, ELT, has the correct first two letters but pushes the third letter further ahead than the pattern demands. The jump from R to T is larger than the consistent step used in the third column earlier. Because it changes the size of the movement for the last letter, ELT does not fit the series.

Option B:
Option B, EKR, keeps E as the first letter but leaves the second and third letters aligned with the previous term rather than moving them forward. That would break the rule that all three columns advance together. Therefore EKR cannot be accepted as the next term.

Option C:
Option C is correct because ELS continues the simple A→B→C→D→E, H→I→J→K→L and O→P→Q→R→S chains and still respects the same gap inside each group. The triple is fully consistent with the way earlier terms were generated. This agreement with both dimensions of the pattern confirms ELS as the right answer.

Option D:
Option D, FLT, changes the starting letter to F and shifts the others in a way that does not match the observed sequences. The columns would no longer increase by exactly one step. As a result, FLT is not compatible with the pattern of the series.

The letters in each group are equally spaced by five positions. AFK is (1,6,11), BGL is (2,7,12), CHM is (3,8,13), DIN is (4,9,14). Next is (5,10,15) = EJO.

Option A:
Option A is correct because E, J and O preserve the constant five-letter spacing and the start-letter progression.

Option B:
Option B ends with Q (17) instead of O (15), breaking the spacing.

Option C:
Option C does not maintain equal gaps of five.

Option D:
Option D starts at F instead of E, breaking the start-letter sequence.
