Which of the following numbers will replace the question mark (?) in the given series?
25, 29, 36, 49, 71,?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 105.
Given series: 25, 29, 36, 49, 71,?
The series follows this pattern:
25 + [4 + (3 × 0)] = 29
29 + [4 + (3 × 1)] = 36
36 + [7 + (3 × 2)] = 49
49 + [13 + (3 × 3)] = 49 + 22 = 71
71 + [22 + (3 × 4)] = 71 + 34 = 105
So, the next term in the series is 105.
