Halfway Between 13 and 623

When you ask "What number is halfway between 13 and 623?" 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=623.

Halfway Between Line

To find the number halfway between 13 and 623, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 623 into our formula, we get:

(13 + 623)/2 = 318

Thus, the number halfway between 13 and 623 is 318.

To check that our answer is correct, we subtract 13 from 318 and subtract 318 from 623 and compare the two numbers:

318 - 13 = 305
623 - 318 = 305

As you can see, the halfway number is 305 higher than 13 and 305 lower than 623. Therefore, our halfway between answer of 318 above is correct.
