# Limit of a sequence with n as a variable, and to the power of n

 P: 5 1. The problem statement, all variables and given/known data Find the limits of the following sequences, if they exist. Justify your answers. {($$\frac{n-1}{n}$$ )$$^{n}$$}$$^{\infty}_{n=1}$$ or maybe $$\sum^{\infty}_{n=1}(\frac{n-1}{n} )^{n}$$ is clearer? 2. Relevant equations I know the whole part that it's a sequence doesn't really matter, that i'm just finding the limit as n $$\rightarrow$$$$\infty$$ but that's not so easy... 3. The attempt at a solution I know that the limit of that (sorry i'm too lazy to retype it) equals the [limit (as n approaches infinity) of ((n-1)/n) ] ^n by the "limit laws" if you want to call them that (the whole think to the nth degree including the limit, sorry if this is really confusing, i'm new to the equation insert thing) but i'm kind of stuck. Because if you evaluate just ((n-1)/n) you end up with infinity over infinity, and it's not something to some other variable that the power is being taken, it's to the same variable, "n", which should be going to infinity anyways, so I'm quite stuck! please help? and thanks!!
