Halfway Between 12 and 520

When you ask "What number is halfway between 12 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=12 and Y=520.

Halfway Between Line

To find the number halfway between 12 and 520, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 12 and 520 into our formula, we get:

(12 + 520)/2 = 266

Thus, the number halfway between 12 and 520 is 266.

To check that our answer is correct, we subtract 12 from 266 and subtract 266 from 520 and compare the two numbers:

266 - 12 = 254
520 - 266 = 254

As you can see, the halfway number is 254 higher than 12 and 254 lower than 520. Therefore, our halfway between answer of 266 above is correct.
