If a,b,c are in A.P. a ,b,d are in G.P. show that a,a-b,d-c are also in G.P.

If a,b,c are in A.P. then :

If a,b,c, d are in G.P., show that : a+b,b+ c and c+d are also in G.P.

If a,b,c are in A.P. and x,y,z are in G.P., then show that x^(b-c).y(c-a).z(a-b)=1 .

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 a, b, c are in A.P, b, c, d are in G.P. and 1/c,1/d,1/e are in A.P. prove that a, c, e are in G.P.
