Which of the following numbers will replace the question mark (?) in the given series?
45, 76, ?, 168, 229
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 117.
Given series: 45, 76, ?, 168, 229
The series follows this pattern:
45 + 31 = 76
76 + 41 = 117
117 + 51 = 168
168 + 61 = 229
So, the missing term in the series is 117.
