Halfway Between 17 and 627

When you ask "What number is halfway between 17 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=17 and Y=627.

Halfway Between Line

To find the number halfway between 17 and 627, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 17 and 627 into our formula, we get:

(17 + 627)/2 = 322

Thus, the number halfway between 17 and 627 is 322.

To check that our answer is correct, we subtract 17 from 322 and subtract 322 from 627 and compare the two numbers:

322 - 17 = 305
627 - 322 = 305

As you can see, the halfway number is 305 higher than 17 and 305 lower than 627. Therefore, our halfway between answer of 322 above is correct.
