Question

Find the missing number in the series - 4,64,13,55,22,46,?

Answer 1

The missing number (?) is "31".

Step-by-step explanation:

The series is 4, 64, 13, 55, 22,4 6,?

The above series has two series.

First,

4, 13, 22, ?

The pattern is adding 9.

4 + 9 = 13, 13 + 9 = 22

∴ ? = 22  + 9 = 31

Second,

64, 55, 46

The pattern is subtract 9.

64 - 9 = 55 and 55 - 9 = 46

Hence, the missing number (?) is "31".
