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

If a^x=b^y=c^z and a,b,c are in G.P. show that 1/x,1/y,1/z are in A.P.

If x,1, and z are in A.P.and x,2, and z are in G.P.then prove that x, and 4,z are in H.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 x,1,z are in AP and x,2,z are in GP,then x,4,z will be in

If x, y and z are in G.P, then show that logx, logy, logz are in A.P.

If reciprocals of (x+y)/2,y, (y+z)/2 are in A.P., show that x,y,z are in G.P.
