The first term of a G.P. is 1. The sum of the third term and fifth term is 90. Find the common ratio of G.P.

If each term of an infinite G.P. is twice the sum of the terms following it, then find the common ratio of the G.P.

the sum of the first six terms of a GP is 9 times the sum of the first three terms. The common ratio is

The sum of the first four terms of an A.P. is 56. The sum of the last four terms is 112. If its first term is 11, then find the number of terms.

Write the GP if the first term a=3, and the common ratio r=2.

The sum of first three terms of a G.P. is and their product is 1. Find the common ratio and the terms.

If the third term of a G.P is P. Then the Product of the first 5 terms of the G.P is
