Halfway Between 89 and 258

When you ask "What number is halfway between 89 and 258?" 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=258.

Halfway Between Line

To find the number halfway between 89 and 258, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 258 into our formula, we get:

(89 + 258)/2 = 173.5

Thus, the number halfway between 89 and 258 is 173.5.

To check that our answer is correct, we subtract 89 from 173.5 and subtract 173.5 from 258 and compare the two numbers:

173.5 - 89 = 84.5
258 - 173.5 = 84.5

As you can see, the halfway number is 84.5 higher than 89 and 84.5 lower than 258. Therefore, our halfway between answer of 173.5 above is correct.
