Question

5,7,10,26,27,63,26,?

Answer 1

Thanks for asking it.

Given series is 5,7,10,26,17,63,26?

The series is made up of two parts :

First sequence : 5,10,17,26

5+5=10
10+7=17
17+9=26


Second sequence : 7,26,63,?

The following pattern is followed in the above sequence :

2³ - 1 =7

3³ - 1 = 26

4³ - 1=63

5³ - 1 =124

So the second series is : 7,26,63,124

Hence complete series is

5,7,10,26,17,63,26,124
