Halfway Between 89 and 178

When you ask "What number is halfway between 89 and 178?" 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=178.

Halfway Between Line

To find the number halfway between 89 and 178, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 178 into our formula, we get:

(89 + 178)/2 = 133.5

Thus, the number halfway between 89 and 178 is 133.5.

To check that our answer is correct, we subtract 89 from 133.5 and subtract 133.5 from 178 and compare the two numbers:

133.5 - 89 = 44.5
178 - 133.5 = 44.5

As you can see, the halfway number is 44.5 higher than 89 and 44.5 lower than 178. Therefore, our halfway between answer of 133.5 above is correct.
