Which of the following numbers will replace the question mark (?) in the given series?
50, 60, 51, 62, 54, 66, 59, 72,?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 66.
Given series: 50, 60, 51, 62, 54, 66, 59, 72,?
The series follows this pattern:
1. 50, 51, 54, 59,?
50 + 1 = 51
51 + 3 = 54
54 + 5 = 59
59 + 7 = 66
2. 60, 62, 66, 72
60 + 2 = 62
62 + 4 = 66
66 + 6 = 72
So, the next term in the series is 66.
