Halfway Between 70 and 638

When you ask "What number is halfway between 70 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=70 and Y=638.

Halfway Between Line

To find the number halfway between 70 and 638, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 70 and 638 into our formula, we get:

(70 + 638)/2 = 354

Thus, the number halfway between 70 and 638 is 354.

To check that our answer is correct, we subtract 70 from 354 and subtract 354 from 638 and compare the two numbers:

354 - 70 = 284
638 - 354 = 284

As you can see, the halfway number is 284 higher than 70 and 284 lower than 638. Therefore, our halfway between answer of 354 above is correct.
