Correct Answer :

Option A

32

Solution :

The correct answer/option is 32.

Let us analyze the given series to find the logic or pattern connecting the numbers:
8, 24, 32, 56, 72, 88

If we divide each number in the given series by 8, we get:
8 ÷ 8 = 1
24 ÷ 8 = 3
56 ÷ 8 = 7
72 ÷ 8 = 9
88 ÷ 8 = 11

The resulting sequence of quotients is 1, 3, 7, 9, 11, which are consecutive odd numbers, except for the missing odd number 5.
Following this prime/odd multiplier pattern (8 × 1, 8 × 3, 8 × 5, 8 × 7, 8 × 9, 8 × 11):
8 × 5 = 40

Therefore, the term in place of 32 should be 40. Hence, 32 is the wrong number in the series.
