Halfway Between 78 and 627

When you ask "What number is halfway between 78 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=78 and Y=627.

Halfway Between Line

To find the number halfway between 78 and 627, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 627 into our formula, we get:

(78 + 627)/2 = 352.5

Thus, the number halfway between 78 and 627 is 352.5.

To check that our answer is correct, we subtract 78 from 352.5 and subtract 352.5 from 627 and compare the two numbers:

352.5 - 78 = 274.5
627 - 352.5 = 274.5

As you can see, the halfway number is 274.5 higher than 78 and 274.5 lower than 627. Therefore, our halfway between answer of 352.5 above is correct.
