Halfway Between 13 and 630

When you ask "What number is halfway between 13 and 630?" 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=630.

Halfway Between Line

To find the number halfway between 13 and 630, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 630 into our formula, we get:

(13 + 630)/2 = 321.5

Thus, the number halfway between 13 and 630 is 321.5.

To check that our answer is correct, we subtract 13 from 321.5 and subtract 321.5 from 630 and compare the two numbers:

321.5 - 13 = 308.5
630 - 321.5 = 308.5

As you can see, the halfway number is 308.5 higher than 13 and 308.5 lower than 630. Therefore, our halfway between answer of 321.5 above is correct.
