SSC CHSL 2025 PYQ — Question 49

We are given the series:

HKLW, IJNU, JIPS, ___, LGTO, MFVM

First letter sequence:

H (8) → I (9) → J (10) → ? → L (12) → M (13)

Pattern: +1 each time.

Missing letter: K (11).

Second letter sequence:

K (11) → J (10) → I (9) → ? → G (7) → F (6)

Pattern: -1 each time.

Missing letter: H (8).

Third letter sequence:

L (12) → N (14) → P (16) → ? → T (20) → V (22)

Pattern: +2 each time.

Missing letter: R (18).

Fourth letter sequence:

W (23) → U (21) → S (19) → ? → O (15) → M (13)

Pattern: -2 each time.

Missing letter: Q (17).

So, the missing cluster is: KHRQ.

Hence, the correct answer is the option (4).
