Which of the following numbers will replace the question mark (?) in the given series?
123, 88, 127, 94, 131, 100, ?, 106, 139
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 135.
Given series: 123, 88, 127, 94, 131, 100, ?, 106, 139
The series follows this pattern:
1. 123, 127, 131, ?, 139
123 + 4 = 127
127 + 4 = 131
131 + 4 = 135
135 + 4 = 139
2. 88, 94, 100, 106
88 + 6 = 94
94 + 6 = 100
100 + 6 = 106
So, the missing term in the series is 135.
