    "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}}}} ?

    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?
