Halfway Between 21 and 483

When you ask "What number is halfway between 21 and 483?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=21 and Y=483.

Halfway Between Line

To find the number halfway between 21 and 483, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 21 and 483 into our formula, we get:

(21 + 483)/2 = 252

Thus, the number halfway between 21 and 483 is 252.

To check that our answer is correct, we subtract 21 from 252 and subtract 252 from 483 and compare the two numbers:

252 - 21 = 231
483 - 252 = 231

As you can see, the halfway number is 231 higher than 21 and 231 lower than 483. Therefore, our halfway between answer of 252 above is correct.
