Which of the following numbers will replace the question mark (?) in the given series?
13, 4, 17, 8, 21,16, 25,?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 32.
Given series: 13, 4, 17, 8, 21,16, 25,?
The series follows this pattern:
1. 13, 17, 21, 25
13 + 4 = 17
17 + 4 = 21
21 + 4 = 25
2. 4, 8, 16,?
4 × 2 = 8
8 × 2 = 16
16 × 2 = 32
So, the next term in the series is 32.
