1. The problem statement, all variables and given/known data Prove by induction that for an integer n where n>1 , http://img3.imageshack.us/img3/5642/prob1q.jpg [Broken] 2. Relevant equations 3. The attempt at a solution Prove P(2) is true then prove P(x) = P(x+1) is true, then it's true for all x That's all I really from proof by induction. It's just not very intuitive to me at all.
