Hello everyone, I'm confused on the directions. It says, Evalute the sum, for n = 1, 2, 3, 4, and 5. Make a conjecture about a formula for this sume for general n, and prove your conjecture by mathematical induction. This is the sum and my work: http://img351.imageshack.us/img351/9551/2pq2.jpg [Broken] I'm having a hard time figuring out that formula, and what exactly is a conjecture? In the other readings and this one they don't say anything about a conjecture. I was thinking that maybe they just want me to place an n where the k is? like n/(n+1)! ? Thanks!
