If a, b, c are in G.P., then=a/b=​

Answer»

Answer:\frac{a}{b}=\frac{b}{c}

Step-by-step explanation

Given: Three no. a , b  & c.

           Given nos. are in GP

To find:  

We use the RESULT of Geometric PROGRESSION which states that If x , y & z are in GP then y² = xz .

⇒ b² = ac

b . b = a . c

transpose c to LHS

transpose b to RH

∴

\frac{a}{b}=\frac{b}{c}
