Best answer
Correct Answer - Option 2 : 54

Given:

9, 16, 30, 54, 79, 114

Calculation:

The logic follows here is:

9 + 7 × 1 = 9 + 7 = 16

16 + 7 × 2 = 16 + 14 = 30

30 + 7 × 3 = 30 + 21 = 51 ≠ 54

51 + 7 × 4 = 51 + 28 = 79

79 + 7 × 5 = 79 + 35 = 114

There should be 51 instead of 54.

∴ 54 is the wrong term.
