Answer 2

Given,

The first, second and the fourth terms of a proportion are 5, 10, and 80 respectively.

To Find,

The third term =?

Solution,

We can solve the question as follows:

It is given that the first, second, and the fourth terms of a proportion are 5, 10, and 80 respectively. We have to find the third term.

Let the third equation be equal to x.

According to the question,

$5:10\: ::\: x:80$

Now, one of the properties of proportion states that the product of extremes is always equal to the product of the means.

Therefore,

$5*80 = 10*x$

$x = \frac{400}{10}$

$x = 10$

Hence, the third term is equal to 10.
