SSC GD Constable (English) - 25th November 2021 Shift 3 • Reasoning • Q91

Select the number from among the given options that can replace the question mark
(?) in the following series.

14, 29, 57, 115, 229,?

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. 459.

The logic used here is:

14, 29, 57, 115, 229,?

(14 × 2) + 1 = 29

(29 × 2) - 1 = 57

(57 × 2) + 1 = 115

(115 × 2) - 1 = 229

(229 × 2) + 1 = 459

Hence, option 4 is the correct answer.
