\frac{1}{p+q}, \frac{1}{q+r}

and

\frac{1}{r+p}

are in

\mathrm{AP}

, then

View answer and explanation

Correct option: B

q^2, p^2

and

r^2

are in AP

Option B (

q^2, p^2, r^2

are in AP) is correct because it is derived from the given AP condition on the reciprocals of (p+q), (q+r), and (r+p).
