Halfway Between 9 and 217

When you ask "What number is halfway between 9 and 217?" 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=217.

Halfway Between Line

To find the number halfway between 9 and 217, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 217 into our formula, we get:

(9 + 217)/2 = 113

Thus, the number halfway between 9 and 217 is 113.

To check that our answer is correct, we subtract 9 from 113 and subtract 113 from 217 and compare the two numbers:

113 - 9 = 104
217 - 113 = 104

As you can see, the halfway number is 104 higher than 9 and 104 lower than 217. Therefore, our halfway between answer of 113 above is correct.
