Halfway Between 100 and 627

When you ask "What number is halfway between 100 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=100 and Y=627.

Halfway Between Line

To find the number halfway between 100 and 627, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 627 into our formula, we get:

(100 + 627)/2 = 363.5

Thus, the number halfway between 100 and 627 is 363.5.

To check that our answer is correct, we subtract 100 from 363.5 and subtract 363.5 from 627 and compare the two numbers:

363.5 - 100 = 263.5
627 - 363.5 = 263.5

As you can see, the halfway number is 263.5 higher than 100 and 263.5 lower than 627. Therefore, our halfway between answer of 363.5 above is correct.
