Letter triplet series ZYX WVU TSR QPO – UGC NET Question

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.
