Halfway Between 13 and 628

When you ask "What number is halfway between 13 and 628?" 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=628.

Halfway Between Line

To find the number halfway between 13 and 628, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 628 into our formula, we get:

(13 + 628)/2 = 320.5

Thus, the number halfway between 13 and 628 is 320.5.

To check that our answer is correct, we subtract 13 from 320.5 and subtract 320.5 from 628 and compare the two numbers:

320.5 - 13 = 307.5
628 - 320.5 = 307.5

As you can see, the halfway number is 307.5 higher than 13 and 307.5 lower than 628. Therefore, our halfway between answer of 320.5 above is correct.
