Homework Help: Limit of (2.3, 2.33, 2.333, )

  1. Nov 2, 2011 #1
    1. The problem statement, all variables and given/known data
    Compute the limit of the following sequences (show work):
    (2.3, 2.33, 2.333, 2.3333, ...)


    3. The attempt at a solution
    Theoretically it approaches 2.333... but I don't think this is the correct answer (and I am not sure how to show it). Does the limit not exist?

    If the sequence happened to be (0.3, 0.33, 0.333, 0.3333, ...), what would the limit of the sequence be? The limit of your sequence is 2 plus the limit of this sequence.

    Remember that a repeating decimal represents a rational number. You should be able to express it as a fraction.

    How "simple" it is depends on how detailed the "show your work" is supposed to be.
