If a, 8, b are in A.P, a, 4 , b are in G.P, a , x, b are in H.P then x =

If a, 8, b are in A.P. , a, 4, b are in G.P. and a , x, b are in H.P. then x=………….

If a,8,b are in A.P and a,4,b are in G.P and a,x ,b are in H.P then x = ………….

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 (x, y) lies on :

If a, b, c are in A.P., a, x, b are in G.P. and b, y, c are in G.P. the point (x, y) lies on

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

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
