Let `a ,b >0,` let `5a-b ,2a+b ,a+2b` be in A.P. and `(b+1)^2, a b+1,(a-1)^2` are in G.P., then the value of `(a^(-1)+b^(-1))` is _______.

Let a,b>0, let 5a-b,2a+b,a+2b be in A.P.and (b+1)^(2),ab+1,(a-1)^(2) are in G.P. then the value of (a^(-1)+b^(-1)) is

If 5a-b, 2a+b, a+2b are in A.P. and (a-1)^(2), (ab+1),(b+1)^(2) are in G.P., a ne 0 , then a is equal to

Suppose a ,b, and c are in A.P. and a^2, b^2 and c^2 are in G.P. If a

If a,A_(1),A_(2),b are in A.P., a,G_(1),G_(2),b are in G.P. and a, H_(1),H_(2),b are in H.P., then the value of G_(1)G_(2)(H_(1)+H_(2))-H_(1)H_(2)(A_(1)+A_(2)) is

If a, b, c are in G.P. and also a, b, c are in A.P. Prove that: 1/a+1/c=2/b

If 1/a,1/b,1/c are in A.P and a,b -2c, are in G.P where a,b,c are non-zero then

If 1/a,1/b,1/c are in A.P and a,b -2c, are in G.P where a,b,c are non-zero then

If 1/a,1/b,1/c are in A.P and a,b -2c, are in G.P where a,b,c are non-zero then

If 1/a,1/b,1/c are in A.P and a,b -2c, are in G.P where a,b,c are non-zero then

If 1/a,1/b,1/c are in A.P and a,b -2c, are in G.P where a,b,c are non-zero then
