In each of the following questions, a series is given, with one term missing. Choose the correct alternative from the given ones that will complete the series.
Let the missing number be x.
The difference between every two consecutive numbers is forming a pattern.
655-637 = 18
637-622 = 15
622-610 = 12
610-601 = 9
As the difference is getting reduced by 3 every time . So 601-x = 6 which implies that the missing number ,x =595
