comment How to make formula for the n-th term of sequence
Ok, I can see it from the graph. But what about the sequence:1, 1/2, 2/3, 3/5, 5/8, 8/13? It has formula a_n+1 = 1/(1+a_n) and I need the formula for the n-th term. The graph doesn't help me now.

comment Packet of cards and probability
I don't know, how does it work here. It is a task about probability. It isn't homework. I found this in some test. After half day of counting and reading articles about combinatorics, I'm not able to solve this. Especially I can't figure out how to count all posibilities.
