Halfway Between 80 and 309

When you ask "What number is halfway between 80 and 309?" 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=309.

Halfway Between Line

To find the number halfway between 80 and 309, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 309 into our formula, we get:

(80 + 309)/2 = 194.5

Thus, the number halfway between 80 and 309 is 194.5.

To check that our answer is correct, we subtract 80 from 194.5 and subtract 194.5 from 309 and compare the two numbers:

194.5 - 80 = 114.5
309 - 194.5 = 114.5

As you can see, the halfway number is 114.5 higher than 80 and 114.5 lower than 309. Therefore, our halfway between answer of 194.5 above is correct.
