Halfway Between 15 and 503

When you ask "What number is halfway between 15 and 503?" 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=503.

Halfway Between Line

To find the number halfway between 15 and 503, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 503 into our formula, we get:

(15 + 503)/2 = 259

Thus, the number halfway between 15 and 503 is 259.

To check that our answer is correct, we subtract 15 from 259 and subtract 259 from 503 and compare the two numbers:

259 - 15 = 244
503 - 259 = 244

As you can see, the halfway number is 244 higher than 15 and 244 lower than 503. Therefore, our halfway between answer of 259 above is correct.
