Halfway Between 13 and 622

When you ask "What number is halfway between 13 and 622?" 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=622.

Halfway Between Line

To find the number halfway between 13 and 622, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 622 into our formula, we get:

(13 + 622)/2 = 317.5

Thus, the number halfway between 13 and 622 is 317.5.

To check that our answer is correct, we subtract 13 from 317.5 and subtract 317.5 from 622 and compare the two numbers:

317.5 - 13 = 304.5
622 - 317.5 = 304.5

As you can see, the halfway number is 304.5 higher than 13 and 304.5 lower than 622. Therefore, our halfway between answer of 317.5 above is correct.
