Halfway Between 89 and 220

When you ask "What number is halfway between 89 and 220?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=89 and Y=220.

Halfway Between Line

To find the number halfway between 89 and 220, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 220 into our formula, we get:

(89 + 220)/2 = 154.5

Thus, the number halfway between 89 and 220 is 154.5.

To check that our answer is correct, we subtract 89 from 154.5 and subtract 154.5 from 220 and compare the two numbers:

154.5 - 89 = 65.5
220 - 154.5 = 65.5

As you can see, the halfway number is 65.5 higher than 89 and 65.5 lower than 220. Therefore, our halfway between answer of 154.5 above is correct.
