Which of the following numbers will replace the question mark (?) in the given series?
3, 5, 9,?, 33, 65
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e.17.
Given series: 3, 5, 9,?, 33, 65
The series follows this pattern:
3 + 2 =5
5 + 4 = 9
9 + 8 = 17
17 + 16 = 33
33 + 32 = 65
So, the missing term in the series is 17.
