After solving the other three problems i moved on to the next challenge,it was a real challenge but i was delighted i found the following:
If you get three every other numbers eg. 1,1,2,3,5,8,13,21
If you choose 1,2,5 they add up to 8 which is an even number,if you choose any other 3 numbers like this it would always be an even number.
