Halfway Between 13 and 625

When you ask "What number is halfway between 13 and 625?" 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=625.

Halfway Between Line

To find the number halfway between 13 and 625, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 625 into our formula, we get:

(13 + 625)/2 = 319

Thus, the number halfway between 13 and 625 is 319.

To check that our answer is correct, we subtract 13 from 319 and subtract 319 from 625 and compare the two numbers:

319 - 13 = 306
625 - 319 = 306

As you can see, the halfway number is 306 higher than 13 and 306 lower than 625. Therefore, our halfway between answer of 319 above is correct.
