Answer 2

The wrong number in 2 , 6 , 16 , 40 , 94 ,192 , 398 is 2

Solution:

As the series given 2, 6, 16, 40, 94, 192, 398

So if we see the series then we would find out that the series follow 2n + 4 series where n is a natural number

2 × 1 + 4 = 6 ……not follow the series

2 × 6 + 4 = 16

2 × 16 + 4 = 36

2 × 40 + 4 = 94

2 × 94 + 4 = 398

So 2 is the wrong number
