Types of series on the basis of Logic :-

1. Simple addition and subtraction series
2. Prime number series
3. Square and cube series

5. Misc

Practice questions to explain the logic

1) 5, 6, 10, 19, 35, ?

2) 11, 13, 17, 19, 23, ?
All are prime numbers so next number in the series will be 29.

4) 4, 9, 25, 49, 121, ?

5) 6, 13, 27, 55, 111, ?
