What should come in place of the question mark '?' in the following number series? 9, 14, 24, 39, 59, ?, 114
84
The given series is 9, 14, 24, 39, 59, ?, 114.
The differences between consecutive terms are 14-9=5, 24-14=10, 39-24=15, 59-39=20.
These differences increase by 5 each time: 5, 10, 15, 20, so the next difference is 25, and the one after that is 30.
The missing term is 59 + 25 = 84, and this is confirmed since 84 + 30 = 114, matching the last given term.
Hence, the answer is 84.
