When you ask "What number is halfway between 8 and 216?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=8 and Y=216.

To find the number halfway between 8 and 216, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 8 and 216 into our formula, we get:
(8 + 216)/2 = 112
Thus, the number halfway between 8 and 216 is 112.
To check that our answer is correct, we subtract 8 from 112 and subtract 112 from 216 and compare the two numbers:
112 - 8 = 104
216 - 112 = 104
As you can see, the halfway number is 104 higher than 8 and 104 lower than 216. Therefore, our halfway between answer of 112 above is correct.
