Question

If 10, 15, x are in continued proportion find the value of x .

Answer 1

Step-by-step explanation:

In continued proportion,

$\frac{a}{b} = \frac{b}{c} \\ {b}^{2} = ac$

Here, a=10, b=15

We have to find x.

So,

${15}^{2} = 10x \\ 225 = 10x \\ x = 22.5 = \frac{45}{2}$

So, x is 45/2 or 22.5.
