Which of the following options will replace the question mark (?) in the given series?

3, 8, 18, 33, 53, ?, 108

Given:3, 8, 18, 33, 53, ?, 108

Logic: The differences are increasing by 5 each time (5, 10, 15, 20, ...).

8 - 3 = 5

18 - 8 = 10

33 - 18 = 15

53 - 33 = 20

Following this pattern, the next difference should be 25 (increasing by 5 again):

53 + 25 = 78

So, the next term in the series is 78.

Thus, correct option is (c).
