Select the number from among the given options that can replace the question mark (?) in the following series.
36, 37, 46, 71, ?, 201
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 120.
Given series: 36, 37, 46, 71, ?, 201
The series follows this pattern:
36 + 12 = 36 + 1 = 37
37 + 32 = 37 + 9 = 46
46 + 52 = 46 + 25 = 71
71 + 72 = 71 + 49 = 120
120 + 92 = 120 + 81 = 201
So, the missing term in the series is 120.
