Halfway Between 9 and 215

When you ask "What number is halfway between 9 and 215?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=9 and Y=215.

Halfway Between Line

To find the number halfway between 9 and 215, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 215 into our formula, we get:

(9 + 215)/2 = 112

Thus, the number halfway between 9 and 215 is 112.

To check that our answer is correct, we subtract 9 from 112 and subtract 112 from 215 and compare the two numbers:

112 - 9 = 103
215 - 112 = 103

As you can see, the halfway number is 103 higher than 9 and 103 lower than 215. Therefore, our halfway between answer of 112 above is correct.
