1. The problem statement, all variables and given/known data Find limn->∞ (1/n)(Ʃk=1 to n ln(2n/(n+k))) 2. Relevant equations 3. The attempt at a solution I'm not sure if this is even a riemann sum at all, but I don't see what else it could be. I wanted to find the riemann portion first to get rid of the sigma notation then find the limit of everything, but I don't have any of the information I need to do the riemann sum or to convert it to an integral.
