    Think about this logically. Which one approaches infinity faster?

    thanks.. the answer is negative infinity, does that mean it diverges, right?

    Actually... It's infinity. Not - Infinity.

    Think. Which n term approaches infinity faster. In other words, does 7n and a square root approach infinity faster?

    if you do L'Hopital's rule, you get 7/(-1/(2sqrtn)) = -14sqrtn limit of that is negative infinity

    Yes, then it is -Infinity. It diverges then.
