If `4, x, 9 are in G.P. , then x =

If 4, x , 16 are in G.P. then x = ………..

If 2+x, 3+x, 9+x are in a G.P., then : x =

IF 4,a,9 are in G.P., then a=………..

suppose x1,x2 are the roots of the equation ax^2+bx+c=0 and x3 and x4 are the roots of the equation px^2+qx+r=0 If a, b, c are in G.P. as well as x_1, x_2, x_3, x_4 are in G.P., then p, q, r are in (i) A.P (ii)G.P (iii)H.P (iv)A.G.P

If a, 8, b are in A.P, a, 4 , b are in G.P, a , x, b are in H.P then x =

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

If a, 8, b are in A.P. , a, 4, b are in G.P. and a , x, b are in H.P. then x=………….

x and y are two positive integers such that 2,x, y are in A.P. and x, y, 9 are in G.P. then show that -x= 4, y= 6.
