Select the wrong term in the series. 74, 98, 134, 182, 244, 314

Solution

The pattern followed in this series is that the difference between consecutive numbers consists of even multiples of 6 from left to right, starting from 24. 74 + (6 × 4) = 74 + 24 = 98 98 + (6 × 6) = 98 + 36 = 134 134 + (6 × 8) = 134 + 48 = 182 182 + (6 × 10) = 182 + 60 = 242 (But the series gives 244) 242 + (6 × 12) = 242 + 72 = 314 As per the pattern, the number 244 is incorrect and should be replaced by 242. Hence, option b.
