If the first term of a G.P. exceeds the second term by 2 and the sum to infinity is 50, find the G.P.

The first term of a geometric progression whose second term is 2 and sum to infinity is 8 will be

The first term of a G.P. is 2 and the sum to infinity is 6. Find the common ratio.

Find the 10th term of a G.P. whose 8th term is 192 and the common ratio is 2.

Find the 12th term of a G.P. whose 8th term is 192 and the common ratio is 2.

The first term of an A.P. is a, the second term is b and last term is c. Show that the sum of A.P. is : ((b+c-2a)(c+a))/(2(b-a)) .

If the 10th term of a G.P. is 9 and 4th term is 4, then its 7th term is :

The common ratio of a G.P. is -4/5 and the sum to infinity is 80/9 . Find the first term.

In a G.P the sum of the first and last terms is 66, the product of the second and the second last term is 128, and the sum of the terms is 126 If the decresing G.P is considered , then find the number of terms

If the sum of first 10 terms of an A.P. is 4 times the sum of its first 5 terms, then find the ratio of first term and common difference.
