Select the number that can replace the (?) in the following series.
22, 33, 66, 88, ?

Given: 22, 33, 66, 88, ?

Logic: The difference between two consecutive numbers is a multiple of 11.

33 - 22 = 11

66 - 33 = 33

88 - 66 = 22

Lets check by option;

Option (a); 84

84 - 88 =  4 (False)

Option (b); 97

97 - 88 = 9 (False)

Option (c); 115

115 - 88 = 27 (False)

Option (d); 165

165 - 88 = 77 (True)

So, only 77 is multiple of 11.

Thus, the correct answer is (d).
