    Determining convergence?

    Hi, I am doing some calculus review and have come to the convergence tests. I am trying to use the comparison test to determine whether the sum from 1 to infinite of 1/(1+ root x) converges. It seems to me that it diverges, since it's comparable to 1/root n, which diverges. However, I can't get a solid comparison going to show it.

    How is this done?
