Which of the following numbers will replace the question mark (?) in the given series?
325, 271, 226, ?, 163, 145, 136
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 190.
Given series: 325, 271, 226, ?, 163, 145, 136
Logic: Decreasing multiples of 9 as series progress
325 - 54 = 271; 271 - 45 = 226; 226 - 36 = 190; 190 - 27 = 163; 163 - 18 = 145; 145 - 9 = 136
