Question

In the following number series, a wrong number is given. Find out the wrong number.

5, 9, 26, 103, 514, 3084

1. 9
2. 26
3. 103
4. 514
5. 3084

Answer 1

Correct Answer - Option 5 : 3084

Given:

5, 9, 26, 103, 514, 3084

Calculation:

The logic follows here is:

(5 × 2) - 1 = 10 - 1 = 9

(9 × 3) - 1 = 27 - 1 = 26

(26 × 4) - 1 = 104 - 1 = 103

(103 × 5) - 1 = 515 - 1 = 514

(514 × 6) - 1 = 3084 - 1 = 3083 ≠ 3084

There should be 3083 instead of 3084.

∴ 3084 is the wrong term
