Which of the following numbers will replace the question mark (?) in the given series?
109, 113, 122, 147,?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 2 i.e. 196.
Given series: 109, 113, 122, 147,?
The series follows this pattern:
109 + 22 = 113
113 + 32 = 122
122 + 52 = 122 + 25 = 147
147 + 72 = 147 + 49 = 196
So, the next term in the series is 196.
