If a,b, c are in H.P. then `a-(b)/(2),(b)/(2),c-(b)/(2)` are in

Assertion: x-a,y-a,z-a are in G.P., Reason: If a,b,c are in H.P. then a- b/2, b- b/2, c- b/2 are in G.P. (A) Both A and R are true and R is the correct explanation of A (B) Both A and R are true R is not te correct explanation of A (C) A is true but R is false. (D) A is false but R is true.

If a,b,c are in H.P., then (b+a)/(b-a)+(b+c)/(b-c)

If a,b,c are in H.P., then (a)/(b+c),(b)/(c+a),(c)/(a+b) will be in

If b-c, 2b-x and b-a are in H.P., then a-(x/2), b-(x/2) and c-(x/2) are in
