Answer 1

Correct Answer - Option 3 : 55,34

The fibonacci series is:

1, 1, 2, 3, 5, 8, 13, 21, 34, 54........

Similarly, the given series is Febonacci but the adjacent terms are interchanged with each other.

So the required series is:

1, 1, 3, 2, 8, 5, 21, 13, 55, 34 

Hence, '55,34' is the correct answer.
