Halfway Between 89 and 221

When you ask "What number is halfway between 89 and 221?" 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=221.

Halfway Between Line

To find the number halfway between 89 and 221, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 221 into our formula, we get:

(89 + 221)/2 = 155

Thus, the number halfway between 89 and 221 is 155.

To check that our answer is correct, we subtract 89 from 155 and subtract 155 from 221 and compare the two numbers:

155 - 89 = 66
221 - 155 = 66

As you can see, the halfway number is 66 higher than 89 and 66 lower than 221. Therefore, our halfway between answer of 155 above is correct.
