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

If a, b, c, are in A.P. ., p , q,r, are in H.P. and ap ,bq, cr are in G.P. then

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

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 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

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

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
