If 5, x, y, z, 405 are the first five terms of a geometric progression, find the values of x, y, and z.

If a, b, c are three consecutive terms of an A.P. and x,y,z are three consecutive terms of a G.P., then the value of x^(b-c).y^(c-a).Z^(a-b) is

If x,y, z are three consecutive terms of a G.P. then prove that (1)/(x+y) + (1)/(y+ z)= (1)/(y) .

If a,b,c are respectively the xth, yth and zth terms of a G.P. then the value of (y-z)log a + (z-x)log b+(x-y) logc :

If 1/(x+y),1/(2y),1/(y+z) are three consecutive terms of an A.P., prove that x, y, z are three consecutive terms of a G.P.

If (1)/(x+y), (1)/(2y) , (1)/(y+z) are the three consecutive terms of an A.P. prove that x ,y,z are the three consecutive terms of a G.P.
