Select the number from among the given options that can replace the question mark (?) in the following series.
7, 16, 41, 94, 251,?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 568.
Given series: 7, 16, 41, 94, 251,?
7 + 9 = 16
16 + (9 × 3 - 2) = 16 + 25 = 41
41 + (25 × 2 + 3) = 41 + 53 = 94
94 + (53 × 3 - 2) = 94 + 157 =251
251 + (157 × 2 + 3) = 251 + 317 = 568
