    This is the question I need help with that I got wrong on my midterm...

    Prove the following statement using mathematical induction:

    show n! is greater than or equal to 3 to the power of (n+1)

    Mathematical induction is basically the following:

    1) Show that if it is true for n, that it is true for n+1.
    2) Show that it is true for a specific value of n (usually n=0 or n=1)

    Of course, if you can find a single value of n for which the assertion is not true, then that makes everything much easier because you are done.

    So, is the assertion true for, say, n=1?
