  1. check your typing.

    If the first and last term of a GS are the same, then r = 1, that is, the terms do not change.
    But then how can there be a difference between the fourth and second term?

    Did you mean..
    "The sum of the 1st and last terms is 42" ?

    Either way, you would have a major problem:
    you have 3 unknowns, a, r, and n
    but only two sets of information.
