Halfway Between 11 and 627

When you ask "What number is halfway between 11 and 627?" 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=627.

Halfway Between Line

To find the number halfway between 11 and 627, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 11 and 627 into our formula, we get:

(11 + 627)/2 = 319

Thus, the number halfway between 11 and 627 is 319.

To check that our answer is correct, we subtract 11 from 319 and subtract 319 from 627 and compare the two numbers:

319 - 11 = 308
627 - 319 = 308

As you can see, the halfway number is 308 higher than 11 and 308 lower than 627. Therefore, our halfway between answer of 319 above is correct.
