Select the number from among the given options that can replace the question mark (?) in the following series.
38, 42, 58, 94, ?, 258
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 158.
Given series: 38, 42, 58, 94, ?, 258
The series follows this pattern:
38 + 22 = 38 + 4 = 42
42 + 42 = 42 + 16 = 58
58 + 62 = 50 + 36 = 94
94 + 82 = 94 + 64 = 158
158 + 102 = 158 + 100 = 258
So, the missing term in the series is 258.
