If `x, 1, z` are in AP and `x, 2, z` are in GP, then `x, 4, z` will be in

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

If x,1,z are in A.P. x,2,z are in G.P., show thast 1/x,1/4,1/z are in A.P.

If x,1,z are in A.P. x,2,z are in G.P., show that 1/x,1/4,1/z are in A.P.

If x, y, z are in A.P.; ax, by, cz are in GP. and 1/a, 1/b, 1/c are in A.P., then x/z+z/x is equal to

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

a, b, c are in A.P. and x, y, z are in G.P. The points (a, x), (b, y), (c, z) are collinear if

3 natural numbers x, y, z are in G.P. & x, y^2, z are in A.P., then the minimum value of x +2y +z is equal to
