" If "x,y,z" are positive numbers in A.P.,then "

If x,y,z are three natural numbers in A.P. such that x+y+z=30 , then the possible number of ordered triplet (x, y, z) is :

IF x,2y,3z are in A.P. where x,y,z are unequal number in a G.P., then the common ratio of this G.P. is (a) 3 (b) 1/3 (c) 2 (d) 1/2

If x, y, z are distinct positive real numbers is A.P. then (1)/(sqrt(x)+sqrt(y)), (1)/(sqrt(z)+sqrt(x)), (1)/(sqrt(y)+sqrt(z)) are in

If x, y, z are distinct positive real numbers is A.P. then (1)/(sqrt(x)+sqrt(y)), (1)/(sqrt(z)+sqrt(x)), (1)/(sqrt(y)+sqrt(z)) are in

Let x,y and z are three positive numbers and P=(x+y+z)/(2); if (p-x):(p-y):(p-z)=3:5:7 then the ratio of x:y:z is

If x,2y, 3z are in A.P. where the distinct numbers x,y,z are in G.P., then the common ratio of the G.P. is :

three 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 ?

Show that x^2+x y+y^2,z^2+xz+x^2, y^2+y z+z^2, are consecutive terms of an A.P., if x ,y and z are in A.P.

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
