Halfway Between 80 and 631

When you ask "What number is halfway between 80 and 631?" 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=631.

Halfway Between Line

To find the number halfway between 80 and 631, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 631 into our formula, we get:

(80 + 631)/2 = 355.5

Thus, the number halfway between 80 and 631 is 355.5.

To check that our answer is correct, we subtract 80 from 355.5 and subtract 355.5 from 631 and compare the two numbers:

355.5 - 80 = 275.5
631 - 355.5 = 275.5

As you can see, the halfway number is 275.5 higher than 80 and 275.5 lower than 631. Therefore, our halfway between answer of 355.5 above is correct.
