Select the option that will correctly replace the question mark (?) in the series.
9, 20, 42, 75, ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 119.
Given series: 9, 20, 42, 75,?
The logic used here is:
9 + 11 = 20
20 + 22 = 42
42 + 33 = 75
75 + 44 = 119
The next term in the series is 119.
Hence, the correct answer is 119.
