Halfway Between 80 and 209

When you ask "What number is halfway between 80 and 209?" 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=209.

Halfway Between Line

To find the number halfway between 80 and 209, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 209 into our formula, we get:

(80 + 209)/2 = 144.5

Thus, the number halfway between 80 and 209 is 144.5.

To check that our answer is correct, we subtract 80 from 144.5 and subtract 144.5 from 209 and compare the two numbers:

144.5 - 80 = 64.5
209 - 144.5 = 64.5

As you can see, the halfway number is 64.5 higher than 80 and 64.5 lower than 209. Therefore, our halfway between answer of 144.5 above is correct.
