Halfway Between 20 and 503

When you ask "What number is halfway between 20 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=20 and Y=503.

Halfway Between Line

To find the number halfway between 20 and 503, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 503 into our formula, we get:

(20 + 503)/2 = 261.5

Thus, the number halfway between 20 and 503 is 261.5.

To check that our answer is correct, we subtract 20 from 261.5 and subtract 261.5 from 503 and compare the two numbers:

261.5 - 20 = 241.5
503 - 261.5 = 241.5

As you can see, the halfway number is 241.5 higher than 20 and 241.5 lower than 503. Therefore, our halfway between answer of 261.5 above is correct.
