Select the number that can replace the question mark (?) in the following series.
14, 28, 31, 124, 129,?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 774.
Given series: 14, 28, 31, 124, 129,?
The series follows this pattern:
14 × 2 = 28
28 + 3 = 31
31 × 4 = 124
124 + 5 = 129
129 × 6 = 774
So, the next term in the series is 774.
