Halfway Between 8 and 521

When you ask "What number is halfway between 8 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=8 and Y=521.

Halfway Between Line

To find the number halfway between 8 and 521, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 8 and 521 into our formula, we get:

(8 + 521)/2 = 264.5

Thus, the number halfway between 8 and 521 is 264.5.

To check that our answer is correct, we subtract 8 from 264.5 and subtract 264.5 from 521 and compare the two numbers:

264.5 - 8 = 256.5
521 - 264.5 = 256.5

As you can see, the halfway number is 256.5 higher than 8 and 256.5 lower than 521. Therefore, our halfway between answer of 264.5 above is correct.
