A series is given with one term missing. Choose the
correct alternative from the given ones that will complete the series. 13, 38, 150, _____, 4478, 31341.Solution
The pattern followed here is: (13 X 3) - 1 = 39 - 1 = 38 (38 X 4) - 2 = 152 - 2 = 150 (150 X 5) - 3 = 750 - 3 = 747 (747 X 6) - 4 = 4482 - 4 = 4478 (4478 X 7) - 5 = 31346 - 5 = 31341 So, '747' will come in place of the blank. The complete series is as follows: 13, 38, 150, 747 , 4478, 31341 Hence, option d.
