Question

Determine the geometric partial sum

is convergent or divergent? can you show me the steps?

Answer 1

Hmm I don't know how to do that actually?

If you could post a problem, maybe then I'll be able to help you

Answer 2

lol sorry about tht.

Answer 3

any finite sum is a number so it "converges"

Answer 4

if the question is
does
\[\sum_{k=1}^{\infty} 3(5^k)=\lim_{n\rightarrow \infty}\sum_{k=1}^n 3\times 5^k\] converge the answer is surely not because the terms do not even go to zero, they get bigger and bigger!
