Hey guys. Can you help me with this problem? I'm trying to plug in a snowflake equation in finding the perimeter of a snowflake on the nth step. The function is as follows:

p:=n->(3*(3/4)^k, k=1..n);
                                   

I'm trying to find the limit of this equation and it's suppose to give me infinity by using this command:

limit(pn(n), n=infinity);     but it's not quite giving me the limit. The limit is...

Hey guys, I'm going to go ahead and post the whole problem along with some of the work that I've done so that it won't look like I'm letting somebody else complete the entire problem. Any help would be appreciated. Here goes:
