Halfway Between 9 and 22

When you ask "What number is halfway between 9 and 22?" 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=22.

Halfway Between Line

To find the number halfway between 9 and 22, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 22 into our formula, we get:

(9 + 22)/2 = 15.5

Thus, the number halfway between 9 and 22 is 15.5.

To check that our answer is correct, we subtract 9 from 15.5 and subtract 15.5 from 22 and compare the two numbers:

15.5 - 9 = 6.5
22 - 15.5 = 6.5

As you can see, the halfway number is 6.5 higher than 9 and 6.5 lower than 22. Therefore, our halfway between answer of 15.5 above is correct.
