Halfway Between 80 and 345

When you ask "What number is halfway between 80 and 345?" 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=345.

Halfway Between Line

To find the number halfway between 80 and 345, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 345 into our formula, we get:

(80 + 345)/2 = 212.5

Thus, the number halfway between 80 and 345 is 212.5.

To check that our answer is correct, we subtract 80 from 212.5 and subtract 212.5 from 345 and compare the two numbers:

212.5 - 80 = 132.5
345 - 212.5 = 132.5

As you can see, the halfway number is 132.5 higher than 80 and 132.5 lower than 345. Therefore, our halfway between answer of 212.5 above is correct.
