Halfway Between 45 and 520

When you ask "What number is halfway between 45 and 520?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=45 and Y=520.

Halfway Between Line

To find the number halfway between 45 and 520, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 520 into our formula, we get:

(45 + 520)/2 = 282.5

Thus, the number halfway between 45 and 520 is 282.5.

To check that our answer is correct, we subtract 45 from 282.5 and subtract 282.5 from 520 and compare the two numbers:

282.5 - 45 = 237.5
520 - 282.5 = 237.5

As you can see, the halfway number is 237.5 higher than 45 and 237.5 lower than 520. Therefore, our halfway between answer of 282.5 above is correct.
