    Integers and induction

    For all integers n ≥ 2, show
    Sigma(1/(n+1))> (13/24)

    P.S. Above the sigma is and underneath it is i=1.

    Sorry, but this question doesn't make any sense. Have you left something out?

    sory it has a sigma:
    For all integers n ≥ 2, show
    Sigma(1/(n+1))> (13/24)

    P.S. Above the sigma is and underneath it is i=1.

    It still doesn't make sense. What is i? What is the upper limit of the summation? Please try to write out the original question.

    Meanwhile, note that \frac{1}{3} + \frac{1}{4} = \frac{7}{12}>\frac{13}{24}, if that is any help.
