Select the number from among the given options that can replace the question mark (?) in the following series.
27, 30, 37, 50, ?, 98
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 69.
Given series: 27, 30, 37, 50, ?, 98
The series follows this pattern:
Prime numbers at the even positions are added.
Prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29 and so on.
27 + 3 = 30
30 + 7 = 37
37 + 13 = 50
50 + 19 = 69
69 + 29 = 98
So, the missing term in the series is 69.
