Halfway Between 45 and 503

When you ask "What number is halfway between 45 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=45 and Y=503.

Halfway Between Line

To find the number halfway between 45 and 503, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 503 into our formula, we get:

(45 + 503)/2 = 274

Thus, the number halfway between 45 and 503 is 274.

To check that our answer is correct, we subtract 45 from 274 and subtract 274 from 503 and compare the two numbers:

274 - 45 = 229
503 - 274 = 229

As you can see, the halfway number is 229 higher than 45 and 229 lower than 503. Therefore, our halfway between answer of 274 above is correct.
