Question
A series follows a specific
pattern as shown below, but one of the terms is incorrect. There is another series that follows the same pattern as the first, but it begins with the incorrect term from the first series. What is the 2nd term of this second series? Series 1: 2, 14, 112, 672, 3360, 13440, 40320Solution
ATQ, Logic in the series is: 2 × 8 = 16 16 × 7 = 112 112 × 6 = 672 672 × 5 = 3360 3360 × 4 = 13440 13440 × 3 = 40320 Wrong term = 14 New series: 14 × 8 = 112 112 × 7 = 784 14, 112, 784 Hence, 2nd term of second series = 112
