How would someone write a shifted geometric sequence in the explicit formula. i believe it requires modification of f(x) = ln(x) however, i haven't been able to figure it out. for example u(n) = u(n-1)(r)-15, let us say u(1) = 28 and r = 2, how would i figure out the 56th term without a graphing calculator using the explicit formula?
