Halfway Between 13 and 624

When you ask "What number is halfway between 13 and 624?" 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=624.

Halfway Between Line

To find the number halfway between 13 and 624, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 624 into our formula, we get:

(13 + 624)/2 = 318.5

Thus, the number halfway between 13 and 624 is 318.5.

To check that our answer is correct, we subtract 13 from 318.5 and subtract 318.5 from 624 and compare the two numbers:

318.5 - 13 = 305.5
624 - 318.5 = 305.5

As you can see, the halfway number is 305.5 higher than 13 and 305.5 lower than 624. Therefore, our halfway between answer of 318.5 above is correct.
