SSC CHSL 2025 PYQ — Question 37

SSC CHSL - 18 Nov 2025 - Shift 2 • Reasoning • Q37

What will come in place of the question mark (?) in the following number series?
1, 8, 2, 27, 3, 64, 4
, ?

Show answer & explanation

Correct answer: A

Explanation

Given sequence:

1, 8, 2, 27, 3, 64, 4, ?

We can separate the sequence into two interleaved series:

Odd positions: 1, 2, 3, 4 → increasing by 1 each time.

Even positions: 8, 27, 64, ? → these are cubes of 2, 3, 4, ?

So, next term is 53=125

Hence, the correct answer is option (1).
