Question

What should come in place of the question mark in the following number series - 5, 8, 6, 9, 7, ?

Answer 1

In this series we can see that there is a recurring +3 and -2 operation to obtain the subsequent terms ie.,
5 + 3 = 8
8 - 2 = 6
&
6 + 3 = 9
9 - 2 = 7
Therefore the next 2 terms will be
7 + 3 = 10
10 - 2 = 8.
