A region of area A bounded by a circle C is divided into n regions, each of area A/n, by drawing circles of radii  r₁ ,r₂ ,r₃ ,....r_n − such that r₁ < r₂ < r₃ <,....r_n-1 concentric with the circle C. If p_m = r_m+1 / r_m  , where m = 1, 2, 3, ... (n - 2), then which one of the following is correct?
