Halfway Between 80 and 641

When you ask "What number is halfway between 80 and 641?" 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=641.

Halfway Between Line

To find the number halfway between 80 and 641, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 641 into our formula, we get:

(80 + 641)/2 = 360.5

Thus, the number halfway between 80 and 641 is 360.5.

To check that our answer is correct, we subtract 80 from 360.5 and subtract 360.5 from 641 and compare the two numbers:

360.5 - 80 = 280.5
641 - 360.5 = 280.5

As you can see, the halfway number is 280.5 higher than 80 and 280.5 lower than 641. Therefore, our halfway between answer of 360.5 above is correct.
