For any three positive real numbers a, b and c, `9(25a^2+b^2)+25(c^2-3ac)=15b(3a+c)` Then: (1) b, c and a are in G.P. (2) b, c and a are in A.P. (3) a, b and c are in A.P (4) a, b and c are in G.P

For any three positive real numbers a , b and c ,9(25 a^2+b^2)+25(c^2-3a c)=15 b(3a+c)dot Then : (1) a ,b and c are in AdotP (2) a ,b and c are in GdotP (3) b ,c and a are in GdotP (4) b , c and a are in AdotP

If a,b, and c are in A.P and b-a,c-b and a are in G.P then a:b:c is

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.

If a,b,c are in A.P and a,b,d are in G.P, prove that a,a-b,d-c are in G.P.

If a, b, c are in A.P. and b-a, c-b, a are in G.P. then a:b:c=?

If a,b,c, are in A.P., b,c,d are in G.P. and c,d,e, are in H.P., then a,c,e are in
