Halfway Between 10 and 520

When you ask "What number is halfway between 10 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=10 and Y=520.

Halfway Between Line

To find the number halfway between 10 and 520, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 10 and 520 into our formula, we get:

(10 + 520)/2 = 265

Thus, the number halfway between 10 and 520 is 265.

To check that our answer is correct, we subtract 10 from 265 and subtract 265 from 520 and compare the two numbers:

265 - 10 = 255
520 - 265 = 255

As you can see, the halfway number is 255 higher than 10 and 255 lower than 520. Therefore, our halfway between answer of 265 above is correct.
