Question
Select the wrong term in the given series. 18,
42, 21, 37, 24, 32, 28, 27Solution
Two series are combined alternatively to form the given series, in first series '3' is added to get the next number starting from 18 and in second series '5' is subtracted to get the next number starting from 42. First series: 18 + 3 = 21 21 + 3 = 24 24 + 3 = 27 Second series: 42 - 5 = 37 37 - 5 = 32 32 - 5 = 27 '28' is the wrong term in the given series.
