Halfway Between 89 and 307

When you ask "What number is halfway between 89 and 307?" 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=307.

Halfway Between Line

To find the number halfway between 89 and 307, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 307 into our formula, we get:

(89 + 307)/2 = 198

Thus, the number halfway between 89 and 307 is 198.

To check that our answer is correct, we subtract 89 from 198 and subtract 198 from 307 and compare the two numbers:

198 - 89 = 109
307 - 198 = 109

As you can see, the halfway number is 109 higher than 89 and 109 lower than 307. Therefore, our halfway between answer of 198 above is correct.
