Question

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

10, 14, 23, 48, 97, 208

1. 10
2. 14
3. 208
4. 97
5. 48

Answer 1

Correct Answer - Option 3 : 208

Given:

10, 14, 23, 48, 97, 208

Calculation:

The logic follows here is:

10 + 2² = 10 + 4 = 14

14 + 3² = 14 + 9 = 23

23 + 5² = 23 + 25 = 48

48 + 7² = 48 + 49 = 97

97 + 11² = 97 + 121 = 218 ≠ 208

There should be 218 instead of 208.

∴ 208 is the wrong term.
