Given that x+y+z=15 when a ,x ,y ,z ,b are in A.P. and 1/x+1/y+1/z=5/3w h e na ,x ,y ,z ,b are in H.P. Then (i) G.M. of a and b is 3 (ii) One possible value of a+2b is 11 (iii) A.M. of a and b is 6 (iv) Greatest value of a-b is 8

Given that x+y+z=15 when a,x,y,z,b are in A.P.and (1)/(x)+(1)/(y)+(1)/(z)+=(5)/(3) when a,x,y,z,b are in H.P.Then G.M.of a and b is 3 One possible value of a+2b is 11 A.M.of a and b is 6 Greatest value of a-b is 8

Given that x+y+z =15 when a,x,y,z,b are in A.P and 1/x+1/y+1/z=5/3 when a,x,y,z,b are in H.P .Then

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

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

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

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

The value of x+y+z is 15 if a,x,y,z,b are in AP while 1/x+1/y+1/z is 5/3 if a,x,y,z,b are in HP ,then the value of a is
