Homework Help: Partial bound question

  1. Dec 10, 2008 #1
    i am given with a series called An
    and series Bn which from a certain place has the same members as An?

    prove or disprove that every partial bound of bn is also a partial bound of An

    ??

    i know that if a series is converges then
    lim inf An=lim sup An

    is that helps?

    how to prove it mathmaticly??
