1. ## "Determine whether the series is convergent or divergent."

Question:
Determine whether the series is convergent or divergent.

Answer:
The answer is Divergent.

I'd appreciate it if someone could explain to me why this is divergent. Does it have anything do with the same summation of 1/n ?

Thanks in advance!

what can you say about the series ...

$-10 \sum{\frac{1}{n^{\frac{3}{5}}}}$ ?

3. Does it diverge BECAUSE OF the comparison test with 1/n and since 1/n diverges and is smaller that's what makes what you said divergent and therefore the whole thing divergent?

close enough.
