Halfway Between 80 and 521

When you ask "What number is halfway between 80 and 521?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=80 and Y=521.

Halfway Between Line

To find the number halfway between 80 and 521, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 521 into our formula, we get:

(80 + 521)/2 = 300.5

Thus, the number halfway between 80 and 521 is 300.5.

To check that our answer is correct, we subtract 80 from 300.5 and subtract 300.5 from 521 and compare the two numbers:

300.5 - 80 = 220.5
521 - 300.5 = 220.5

As you can see, the halfway number is 220.5 higher than 80 and 220.5 lower than 521. Therefore, our halfway between answer of 300.5 above is correct.
