Halfway Between 13 and 636

When you ask "What number is halfway between 13 and 636?" 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=636.

Halfway Between Line

To find the number halfway between 13 and 636, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 636 into our formula, we get:

(13 + 636)/2 = 324.5

Thus, the number halfway between 13 and 636 is 324.5.

To check that our answer is correct, we subtract 13 from 324.5 and subtract 324.5 from 636 and compare the two numbers:

324.5 - 13 = 311.5
636 - 324.5 = 311.5

As you can see, the halfway number is 311.5 higher than 13 and 311.5 lower than 636. Therefore, our halfway between answer of 324.5 above is correct.
