If a,x, and b and b are in A.P .., a,y , and a,z,b are in H.P such that x=9z and `a gt 0, b gt 0` then

If a,x,b are in A.P.,a,y,b are in G.P. and a,z,b are in H.P. such that x=9z and gt0,bgt0 , then

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

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=………….

If a+c , a+b , b+c are in G.P and a,c,b are in H.P. where a , b , c gt 0 , then the value of (a+b)/(c ) is

If x ,1,a n dz are in A.P. and x ,2,a n dz are in G.P., then prove that x ,a n d4,z are in H.P.

If a,b,c are in H.P , b,c,d are in G.P and c,d,e are in A.P. , then the value of e is

If x,y and z are in A.P ax,by and cz in G.P and a, b, c in H.P then prove that x/z+z/x=a/c+c/a

a ,b ,c x in R^+ such that a ,b ,a n dc are in A.P. and b ,ca n dd are in H.P., then a b=c d b. a c=b d c. b c=a d d. none of these

If x, y, z are in A.P then e^(-x) , e^(-y) and e^(-z) are

If x ,ya n dz are in A.P., a x ,b y ,a n dc z in G.P. and a ,b ,c in H.P. then prove that x/z+z/x=a/c+c/a .
