Select the number from among the given options that can replace the question mark (?) in the following series.
153, 149, 143, 135,?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 125.
Given series: 153, 149, 143, 135,?
The series follows this pattern:
153 - 4 = 149
149 - 6 = 143
143 - 8 = 135
135 - 10 = 125
So, the next term in the series is 125.
