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.
