{A_1},\,\,{A_2},\,\,{A_3}

denote respectively the areas of an inscribed polygon of

2n

sides, inscribed polygon of

n

sides and circumscribed polygon of

n

sides, then

{A_2},\,\,{A_1},\,\,{A_3}

are in

View answer and explanation

Correct option: B

G.P.

Option B (G.P.) is correct because the areas

{A_2}, {A_1}, {A_3}

form a geometric progression, as shown by the relationship

{A_1}^2 = {A_2}{A_3}
