Question

find the value of x if 25, x and 9 are in continued proportion​

Answer 1

Given

• 25 : x = x : 9

To find

• The value of x

Solution

We know that:-

$\boxed{\rm{Product ~of~means = Product ~of ~extremes}}$

⇒ x² = 25 × 9

⇒ x² = 225

⇒ x = $\sqrt{225}$

⇒ x = 15

•°• the value of x = 15
