Select the number from among the given options that can replace the question mark (?) in the following series.
18, 29, 42, 59, 78, 101,?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 130.
Given series: 18, 29, 42, 59, 78, 101,?
The series follows the pattern:
18 + 11 = 29
29 + 13 = 42
42 + 17 = 59
59 + 19 = 78
78 + 23 = 101
101 + 29 = 130
So, the next term in the series is 130.
