Select the number from among the given options that can replace the question mark (?) in the following series.
5, 9, 18, 34,? , 95
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 59.
Given series: 5, 9, 18, 34,? , 95
The series follows this pattern:
5 + 22 = 5 + 4 = 9
9 + 32 = 9 + 9 = 18
18 + 42 = 18 + 16 = 34
34 + 52 = 34 +25 = 59
59 + 62 = 59 + 36 = 95
So, the missing term in the series is 59.
