If `S_(1), S_(2), S_(3)` be respectively the sums of n, 2n and 3n terms of a G.P., prove that, `S_(1)(S_(3) - S_(2)) = (S_(2) - S_(1))^(2)`.

If S_(1), S_(2) and S_(3) be respectively the sum of n, 2n and 3n terms of a G.P. Prove that S_(1) (S_(3)-S_(2))= (S_(2)-S_(1))^(2) .

If S_(1),S_(2) andS _(3) be respectively the sum of n,2n and 3n terms of a G.P.prove that S_(1)(S_(3)-S_(2))=(S_(2)-S_(1))^(2)

If S_1,S_2a n dS_3 be respectively the sum of n, 2n and 3n terms of a G.P., prove that S_1(S_3-S_2)=(S_2-S_1)^2

If S_1,S_2 and S_3 be respectively the sum of n, 2n and 3n terms of a G.P., prove that S_1(S_3-S_2)=((S_2)-(S_1))^2

If S_1 , S_2 and S_3 are respectively the sum of n, 2n and 3n terms of a G.P., then prove that S_1(S_3 - S_2) = (S_2 - S_1)^2 .

If S_(1), S_(2) , and S_(3) are, respectively, the sum of n, 2n and 3n terms of a G.P., then (S_(1)(S_(3)-S_(2)))/((S_(2)-S_(1)^(2)) is equal to
