Question 76

What is the next term in the following series:
22B, 2Y, 24D, 4W, 26F, ...........

Solution

Here it has two parts, one numerical and the other is alphabet. Here we are considering 1 to 26, so after 26 it again starts repeating from 1. So 26+1 will mean 0+1 and so on

22B - 22= 26-4 ; B= +2

2Y : 2= 26+2 ; Y= -2

24D: 24 = 26-2 ; D= +4

4W : 4= 26+4 ; W = -4

26F : 26= 26-0 ; F = +6

6U : 6= 26+6 ; U= -6

So option B is correct.
