` a,b,c,d` are in GP are in ascending order such that a+d=112 and b+c=48 If the GP is continued with as the first term, then the sum of the first six term is:

Let a, b, c and d are in a geometric progression such that a lt b lt c lt d, a + d=112 amd b+c=48 . If the geometric progression is continued with a as the first term, then the sum of the first six terms is

If the second and fifth terms of a GP are 24 and 3 respectively, then the sum of first six terms is

A G.P. has first term 729 and 7th term 64. Find the sum of its first 7 terms.

The second term of a GP is 24 and its fifth term is 81. Find the sum of its first five terms.

The first term of a GP is 27 and its 8th terms is 1/81 . Find the sum of its first 10 terms.

If 2^(nd) term of GP is 2 and the sum of infinite terms is 8 find the first term

If the sum of first n terms of a G.P. is s and the sum of its first 2n terms is 5S, then show that the sum of its first 3n terms is 21S .

If the sum of first n terms of a G.P. is S and the sum of its first 2n terms is 5S, then show that the sum of its first 3n terms is 21S.

If a, b, c are in AP and a, b, d are in GP, show that a, (a-b) and (d-c) are in GP.
