Question
Select the number from among the given options that can
replace the question mark in the following series. 4, 11, 31, 90, 266, 793, ?Solution
The logic followed in this series involves multiplying the previous term by a constant and subtracting an increasing value. (4 x 3) - 1 = 11 (11 x 3) - 2 = 31 (31 x 3) - 3 = 90 (90 x 3) - 4 = 266 (266 x 3) - 5 = 793 (793 x 3) - 6 = 2373
