Let

a^2, b^2, c^2

be three distinct numbers in A.P. If

a b+b c+c a=1

then

(b+c),(c+a)

and

(a+b)

are in:

View answer and explanation

Correct option: C

H.P.

Option C (H.P.) is correct because given

a^2, b^2, c^2

are in A.P. and

ab+bc+ca=1

, it can be shown that

(b+c), (c+a), (a+b)

are in H.P.
