Which of the following numbers will replace the question mark (?) in the given series?
13, 26, 23, 115, 108,?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 1188.
Given series: 13, 26, 23, 115, 108,?
The series follows this pattern:
13 × 2 = 26
26 - 3 = 23
23 × 5 = 115
115 - 7 = 108
108 × 11 = 1188
So, the next term in the series is 1188.
