.Find the G.P., if the common ratio of G.P. is 3, nth term is 486 and sum of first n terms is 728.

Find the third term of a G.P. whose common ratio is 3 and the sum of whose first seven terms is 2186

A GP has common ratio 3, last term 486, if the sum of its terms is 728, find its first term.

In a G.P if the first term is 3, nth term is 96 and the sum of n terms is 189, then the number of terms is

The first term of a G.P. is 3 and the common ratio is 2. Then the sum of first eight terms of the G.P. is

The fifth term of a G.P. is 32 and common ratio is 2 , then the sum of first 14 terms of the G.P. is

The fifth term of a G.P. is 32 and common ratio is 2 , then the sum of first 14 terms of the G.P. is

A geometric progression has common ratio = 3 and last term = 486. If the sum of its terms is 728, find its first term.
