Can someone help me with these problems Thanks!
1. Determine whether the sequence converges or diverges, if converges, find limit. an = n/1+ squareroot n
I divided top and bottom by 1/n and got 1/0 + 1/0 = 0 = converges
2. find the sum of series e^n/3^n-1 I got no idea what to do, please help me, thanks again!
