Halfway Between 13 and 637

When you ask "What number is halfway between 13 and 637?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=13 and Y=637.

Halfway Between Line

To find the number halfway between 13 and 637, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 637 into our formula, we get:

(13 + 637)/2 = 325

Thus, the number halfway between 13 and 637 is 325.

To check that our answer is correct, we subtract 13 from 325 and subtract 325 from 637 and compare the two numbers:

325 - 13 = 312
637 - 325 = 312

As you can see, the halfway number is 312 higher than 13 and 312 lower than 637. Therefore, our halfway between answer of 325 above is correct.
