Halfway Between 15 and 623

When you ask "What number is halfway between 15 and 623?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=15 and Y=623.

Halfway Between Line

To find the number halfway between 15 and 623, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 623 into our formula, we get:

(15 + 623)/2 = 319

Thus, the number halfway between 15 and 623 is 319.

To check that our answer is correct, we subtract 15 from 319 and subtract 319 from 623 and compare the two numbers:

319 - 15 = 304
623 - 319 = 304

As you can see, the halfway number is 304 higher than 15 and 304 lower than 623. Therefore, our halfway between answer of 319 above is correct.
