Which of the following numbers will replace the question mark (?) in the given series?
13, 14, 23, 48, 97, 178, ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 299.
Given series: 13, 14, 23, 48, 97, 178, ?
The series follows this pattern:
13 + 12 = 14
14 + 32 = 14 + 9 = 23
23 + 52 = 23 + 25 = 48
48 + 72 = 48 + 49 = 97
97 + 92 = 97 + 81 = 178
178 + 112 = 178 + 121 = 299
So, the next term in the series is 299.
