Halfway Between 99 and 503

When you ask "What number is halfway between 99 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=99 and Y=503.

Halfway Between Line

To find the number halfway between 99 and 503, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 99 and 503 into our formula, we get:

(99 + 503)/2 = 301

Thus, the number halfway between 99 and 503 is 301.

To check that our answer is correct, we subtract 99 from 301 and subtract 301 from 503 and compare the two numbers:

301 - 99 = 202
503 - 301 = 202

As you can see, the halfway number is 202 higher than 99 and 202 lower than 503. Therefore, our halfway between answer of 301 above is correct.
