Halfway Between 17 and 503

When you ask "What number is halfway between 17 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=17 and Y=503.

Halfway Between Line

To find the number halfway between 17 and 503, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 503 into our formula, we get:

(17 + 503)/2 = 260

Thus, the number halfway between 17 and 503 is 260.

To check that our answer is correct, we subtract 17 from 260 and subtract 260 from 503 and compare the two numbers:

260 - 17 = 243
503 - 260 = 243

As you can see, the halfway number is 243 higher than 17 and 243 lower than 503. Therefore, our halfway between answer of 260 above is correct.
