In the attachments I have answered this problem.
We know that general form of GP is
a, ar, ar^2.............
Make use of this I have proved the given problem.
See the attachments for detailed solution.

GEOMETRIC PROGRESSION :
A sequence a1, a2, a3 ………….. an is called a geometric sequence if a(ⁿ+1) = aⁿr, where r is a non zero constant. Here, a1 is the first term and the constant r is called common ratio. The sequence is also called a geometric progression(G.P)
a1 = a , r = a(ⁿ+1)/ aⁿ
General term of a geometric sequence is
tn = arⁿ-1
SOLUTION IS IN THE ATTACHMENT.
HOPE THIS WILL HELP YOU..
