Select the number from among the given options that can replace the question mark
(?) in the following series.
24, 40, 64, 104, ?, 312
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 176.
Given series: 24, 40, 64, 104, ?, 312
The series follows this pattern:
24 + 16 = 40
40 + (16 + 8 ) = 40 + 24 = 64
64 + (24 + 16) = 64 + 40 = 104
104 + (40 + 32) = 104 + 72 = 176
176 + (72 + 64) = 176 + 136 = 312
So, the missing term in the series is 176.
