Halfway Between 88 and 638

When you ask "What number is halfway between 88 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=88 and Y=638.

Halfway Between Line

To find the number halfway between 88 and 638, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 88 and 638 into our formula, we get:

(88 + 638)/2 = 363

Thus, the number halfway between 88 and 638 is 363.

To check that our answer is correct, we subtract 88 from 363 and subtract 363 from 638 and compare the two numbers:

363 - 88 = 275
638 - 363 = 275

As you can see, the halfway number is 275 higher than 88 and 275 lower than 638. Therefore, our halfway between answer of 363 above is correct.
