Which of the following numbers will replace the question mark (?) in the given series?
3, 7, 5, 61, 363,?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 3367.
Given series: 3, 7, 5, 61, 363,?
The series follows this pattern:
3 × 1 + (2)2 = 7
7 × 3 - (4)2 = 5
5 × 5 + (6)2 = 61
61 × 7 - (8)2 = 363
363 × 9 + (10)2 = 3367
So, the next term in the series is 3367.
