Question

What is the formula for product of n tens of GP??

Answer 1

Answer:

If the first and the nth term of a G.P. are a ad b, respectively, and if P is the product of n terms, prove that P2 = (ab)n. The first term of the G.P is a and the last term is b. Therefore, the G.P. is a, ar, ar2, ar3, … arn–1, where r is the common ratio

Answer 2

The general form of a GP is a, ar, ar2, ar3 and so on. The nth term of a GP series is Tn = arn-1, where a = first term and r = common ratio = Tn/Tn-1) . ... The nth term from the end of the G.P. with the last term l and common ratio r is l/(r(n-1)) .
