Answer :

[tex]\frac{3000+4000}{2}=\frac{7000}{2}\to\boxed{3500}[/tex]

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

For this, we use the following relationship:

[tex] n = \frac{x1+x2}{2} [/tex]

Substituting values we have:

[tex] n = \frac{3000+4000}{2} [/tex]

Rewriting and simplifying the expression we have:

[tex] n = \frac{7000}{2}

n= 3500 [/tex]

Answer:

A number that is halfway between 3000 and 4000 is:

3500
