Question

What number is halfway between 3000 and 4000

Answer 1

$\frac{3000+4000}{2}=\frac{7000}{2}\to\boxed{3500}$

Answer 2

For this case, what we should do is calculate the average of 3000 and 4000.

For this, we use the following relationship:

$n = \frac{x1+x2}{2}$

Substituting values we have:

$n = \frac{3000+4000}{2}$

Rewriting and simplifying the expression we have:

$n = \frac{7000}{2} \\n= 3500$

Answer:

A number that is halfway between 3000 and 4000 is:

3500
