Q. If `a,b,c` are in AP, then `bc,ca,ab` are in ?

If a,b,c are in A.P., then (bc)/(ca+ab),(ca)/(bc+ab),(ab)/(bc+ca)

If (b+c)/(a),(c+a)/(b),(a+b)/(c) are in A.P.prove that :bc,ca,ab are in A.P.

If a,b,c are in H.P and ab+bc+ca=15 then ca=

If a,b,c are in AP, show that (a(b+c))/(bc) , (b (c+a))/(ca), (c(a+b))/(ab) , are also in AP.

If a, b, c are in A.P., then prove that : (i) ab+bc=2b^(2) (ii) (a-c)^(2)=4(b^(2)-ac) (iii) a^(2)+c^(2)+4ca=2(ab+bc+ca).

If a,b,c are in A.P then a+(1)/(bc),b+(1)/(ca),c+(1)/(ab) are in

If a,b,c are in A.P,prove that (1)/(bc),(1)/(ca),(1)/(ab), is also in A.P.

If a, b, c are in A.P. that the following are also in A.P:(i) (1)/(bc),(1)/(ca),(1)/(ab)

If a,b,c are in AP show that (i) 1/(bc) ,1/(ca),1/(ab) are in AP.
