Halfway Between 80 and 229

When you ask "What number is halfway between 80 and 229?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=80 and Y=229.

Halfway Between Line

To find the number halfway between 80 and 229, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 229 into our formula, we get:

(80 + 229)/2 = 154.5

Thus, the number halfway between 80 and 229 is 154.5.

To check that our answer is correct, we subtract 80 from 154.5 and subtract 154.5 from 229 and compare the two numbers:

154.5 - 80 = 74.5
229 - 154.5 = 74.5

As you can see, the halfway number is 74.5 higher than 80 and 74.5 lower than 229. Therefore, our halfway between answer of 154.5 above is correct.
