    Add 1+2 = 3, 3+2=5, 5+3=8 etc. It's just the two numbers added and then the following two.

    Answer is 8,34

    No bother, eh it's quite a strange question for an application for Penny's don't you think?

    If you just google for 1,2,3,5 - the Wikipedia article on fibonacci pops up at the top of the list.

    This ( to me at least ) was not an obvious thing to do - but I am finding out lately that Google can do a great job even with somewhat cryptic search criteria.
