Halfway Between 11 and 623

When you ask "What number is halfway between 11 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=11 and Y=623.

Halfway Between Line

To find the number halfway between 11 and 623, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 623 into our formula, we get:

(11 + 623)/2 = 317

Thus, the number halfway between 11 and 623 is 317.

To check that our answer is correct, we subtract 11 from 317 and subtract 317 from 623 and compare the two numbers:

317 - 11 = 306
623 - 317 = 306

As you can see, the halfway number is 306 higher than 11 and 306 lower than 623. Therefore, our halfway between answer of 317 above is correct.
