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.

1/a, 1/b and 1/c are in A.P. Show that bc, ca, and ab are also in A.P.

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 H.P and ab+bc+ca=15 then ca=

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 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, prove that 1/(bc),1/(ca),1/(ab) are also in A.P.
