Answer 2

Answer :

We have,

• The numbers 6,9,x
• These numbers are in continued proportion.

To do,

• Find the value of x

We know that,

• In continued proportion the mid term is used twice for both the side.

Taking this, solve for x

= 6 : 9 :: 9 : x

= $\dfrac{6}{9}$ = $\dfrac{9}{x}$

Cross multiply

= 6x = 9 × 9

= 6x = 81

= x = $\dfrac{81}{6}$

= x = 13.5

•°• The value of x is 13.5.
