Question 250559: I need help with my Algebra please. It says tell whether each sequence is convergent or divergent. If it is convergent find it sum.
1. infinite E (2/3)^n n=0
2. infinite E (-4/11)^n n=0
3. infinite E (5^k+1)/3^k n=0
4. infinite E (3^n-1)/4^n n=1

Hint: Recall that the series is convergent if and it diverges otherwise. If it converges, then

So for the first problem, let which makes and . Because , this means that . Use the same idea for the rest of the problems.
