Halfway Between 89 and 243

When you ask "What number is halfway between 89 and 243?" 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=243.

Halfway Between Line

To find the number halfway between 89 and 243, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 243 into our formula, we get:

(89 + 243)/2 = 166

Thus, the number halfway between 89 and 243 is 166.

To check that our answer is correct, we subtract 89 from 166 and subtract 166 from 243 and compare the two numbers:

166 - 89 = 77
243 - 166 = 77

As you can see, the halfway number is 77 higher than 89 and 77 lower than 243. Therefore, our halfway between answer of 166 above is correct.
