Hi, 1. The problem statement, all variables and given/known data Just having some troubles with a proof i have been asked to do, (sorry for not knowing the math code) basically, f(1)=0, f(2)=1/3 and f(n)= ((n-1)/(n+1))*f(n-2) and i've come up with the conjecture that f(n) = 0 when n is odd, and = 1/(n+1) when n is even. and i have to prove my conjecture, this is where i'm stuck, 2. Relevant equations anyone care to point me in the right direction? 3. The attempt at a solution not really sure what method to use, induction?
