Halfway Between 80 and 355

When you ask "What number is halfway between 80 and 355?" 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=355.

Halfway Between Line

To find the number halfway between 80 and 355, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 355 into our formula, we get:

(80 + 355)/2 = 217.5

Thus, the number halfway between 80 and 355 is 217.5.

To check that our answer is correct, we subtract 80 from 217.5 and subtract 217.5 from 355 and compare the two numbers:

217.5 - 80 = 137.5
355 - 217.5 = 137.5

As you can see, the halfway number is 137.5 higher than 80 and 137.5 lower than 355. Therefore, our halfway between answer of 217.5 above is correct.
