If a,x,b are in A.P.,a,y,b are in G.P. and a,z,b are in H.P. such that x=9z and `gt0,bgt0`, then

If a,x,b are in A.P.,a,y,b are in G.P. and a,z,b are in H.P. such that x=9z and agt0,bgt0 , then

If a,x,b are in AP, a,y,b are in GP and a,z,b are in HP such that x=9z and a > 0 , b > 0 , where a ne b , b ne 0 then x^2/y^2 is _________.

a,b,x are in A.P.,a,b,y are in G.P. and a,b,z are in H.P. then:

Let a, x, b are in A.P., a, y, b are in G.P. and a, z, b are in H.P. If x = y + 2 and a = 5z then (where a, b, c e R*)

If x,1,z are in A.P. and x,2,z are in G.P., then x,4,z are in

Let a,x,b be in A.P , a,y,b be in G.P and a,z,b be in H.P . If x=y+2 and a=5z , then

If a,b,c are in A.P., a,x,b are in G.P. and b,y,c are in G.P. then a^(2),b^(2),y^(2) are in
