Halfway Between 15 and 523

When you ask "What number is halfway between 15 and 523?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=15 and Y=523.

Halfway Between Line

To find the number halfway between 15 and 523, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 523 into our formula, we get:

(15 + 523)/2 = 269

Thus, the number halfway between 15 and 523 is 269.

To check that our answer is correct, we subtract 15 from 269 and subtract 269 from 523 and compare the two numbers:

269 - 15 = 254
523 - 269 = 254

As you can see, the halfway number is 254 higher than 15 and 254 lower than 523. Therefore, our halfway between answer of 269 above is correct.
