Select the number that can replace the question mark (?) in the following series.

3, 2, 2, 3, 8, ?
 

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. 35.

Given series: 3, 2, 3, 8, 31, ?

2nd term = (1st term × 1) - 1 = (3 × 1) - 1 = 2

3rd term = (2nd term × 1) + 0 = (2 × 1) + 0 = 2

4th term = (3rd term × 2) - 1 = (2 × 2) - 1 = 3

5th term = (4th term × 2) + 2 = (3 × 2) + 2 = 8

6th term = (5th term × 4) + 3 = (8 × 4) + 3 = 35
