Halfway Between 89 and 321

When you ask "What number is halfway between 89 and 321?" 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=321.

Halfway Between Line

To find the number halfway between 89 and 321, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 321 into our formula, we get:

(89 + 321)/2 = 205

Thus, the number halfway between 89 and 321 is 205.

To check that our answer is correct, we subtract 89 from 205 and subtract 205 from 321 and compare the two numbers:

205 - 89 = 116
321 - 205 = 116

As you can see, the halfway number is 116 higher than 89 and 116 lower than 321. Therefore, our halfway between answer of 205 above is correct.
