Here is the problem:

geometric series is: n=1 to infinity e^n/2^n

here is what I did: (e/2)^n r= e/2 e/2>1

since r>1 the series diverges, is this correct? Do I need to explain this more for a complete answer?

The other one is a geometric series n=0 to infinity 1/Sqrt(2)^n

I plugged in 0 for n and my series is as follows:

1 +1/Sqrt(2) + 1/2 + 1/sqrt(2)^3 + ...

this series diverges, do I need to explain these further?

Am I doing these correctly?

Thank you,

Keith
