Halfway Between 12 and 638

When you ask "What number is halfway between 12 and 638?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=12 and Y=638.

Halfway Between Line

To find the number halfway between 12 and 638, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 12 and 638 into our formula, we get:

(12 + 638)/2 = 325

Thus, the number halfway between 12 and 638 is 325.

To check that our answer is correct, we subtract 12 from 325 and subtract 325 from 638 and compare the two numbers:

325 - 12 = 313
638 - 325 = 313

As you can see, the halfway number is 313 higher than 12 and 313 lower than 638. Therefore, our halfway between answer of 325 above is correct.
