1. The problem statement, all variables and given/known data Find the exact sum of the series: 1/1!3 + 1/2!4 + ... + 1/n!(n+2) 2. Relevant equations 3. The attempt at a solution The only series I know that look like this are e^x and ln(x) (centered at x = 1). But I do not know how to combine them and I'm not even sure if that's what I'm supposed to do. e^x = 1 + x + x^2/2! + ... + x^n/n! ln(x) = (x-1) -(1/2)(x-1)^2 + (1/3)(x-1)^3 ... ln(x) is missing the factorials and has alternating signs. I tried messing around with its input value but to no avail. Any help would be appreciated.
