What should come in place of the question mark (?) in the given series?
28 39 53 70 90 ?
113
Observe the differences between consecutive numbers in the series:
39 - 28 = 11,
53 - 39 = 14,
70 - 53 = 17,
90 - 70 = 20.
The differences are increasing by 3 each time (11, 14, 17, 20), so the next difference should be 20 + 3 = 23.
Thus, the next number in the series should be 90 + 23 = 113.
Therefore, the correct answer is 113.
