Which of the following numbers will replace the question mark (?) in the given series?
54, 58.7, 64.4, 71.1, 78.8,?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 87.5.
Given series: 54, 58.7, 64.4, 71.1, 78.8,?
The series follows this pattern:
54 + 4.7 = 58.7
58.7 + 5.7 = 64.4
64.4 + 6.7 = 71.1
71.1 + 7.7 = 78.8
78.8 + 8.7 = 87.5
So, the next term in the series is 87.5.
