Which number will replace the question mark(?) in the following series?
17, 51, 58, 116, 123, 123, ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 130.
Given series: 17, 51, 58, 116, 123, 123, ?
The series follows the pattern:
17 × 3 = 51
51 + 7 = 58
58 × 2 = 116
116 + 7 = 123
123 × 1 = 123
123 + 7 = 130
So, the next term in the series is 130.
