Halfway Between 4 and 503

When you ask "What number is halfway between 4 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=4 and Y=503.

Halfway Between Line

To find the number halfway between 4 and 503, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 503 into our formula, we get:

(4 + 503)/2 = 253.5

Thus, the number halfway between 4 and 503 is 253.5.

To check that our answer is correct, we subtract 4 from 253.5 and subtract 253.5 from 503 and compare the two numbers:

253.5 - 4 = 249.5
503 - 253.5 = 249.5

As you can see, the halfway number is 249.5 higher than 4 and 249.5 lower than 503. Therefore, our halfway between answer of 253.5 above is correct.
