Homework Help: Confused in series concept!

  1. Dec 13, 2008 #1
    I have a problem understanding the divergence of series.. There is a n-th term test that u first apply on the general term of the series and if its limit is not equal 0 then the series is divergent.. When i apply that test sometime i get it wrong and sometime not.. When can i apply this test? is there any special conditions for it? or it should always work.

    Please show us examples of what you mean by getting it wrong. The nth term test can tell you if a series diverges, but not all series that diverge fail the nth term test.
