SSC CHSL 2025 PYQ — Question 42

Series:

Z73, Y79, X83, W89, ?

Letters:

Z → Y → X → W

Each time the letter moves one step backward in the alphabet.

Z (-1) → Y (-1) → X (-1) → W

So next letter will be:

V

Numbers:

the numbers are all prime numbers: 73, 79, 83, 89 — the next prime after 89 is 97.

So the next term is V97.

Hence, the correct answer is option (2).
