What should come in place of ‘?’ in the given series?
32 52 68 80 88 ?

The correct answer is
92

Number Series Logic Explained

The question presents a number series: 32, 52, 68, 80, 88, ?. We need to find the missing number represented by '?'.

Identifying the Series Pattern

To find the pattern, let's calculate the difference between consecutive terms:

  • $52 - 32 = 20$
  • $68 - 52 = 16$
  • $80 - 68 = 12$
  • $88 - 80 = 8$

The differences are 20, 16, 12, 8.

Calculating the Next Term

Observe the pattern in the differences: 20, 16, 12, 8. Each difference decreases by 4.

  • $20 - 4 = 16$
  • $16 - 4 = 12$
  • $12 - 4 = 8$

Following this pattern, the next difference should be $8 - 4 = 4$.

To find the missing number, add this next difference (4) to the last term in the series (88):

$88 + 4 = 92$

Therefore, the number that should come in place of '?' is 92.
