 May 16 comment How to make formula for the n-th term of sequenceOk, 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.

You are right. Apr 22 awarded Scholar Apr 22 accepted Packet of cards and probability Apr 22 awarded Student Apr 22 comment Packet of cards and probabilityI 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. Apr 22 asked Packet of cards and probability
