Halfway Between 80 and 687

When you ask "What number is halfway between 80 and 687?" 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=687.

Halfway Between Line

To find the number halfway between 80 and 687, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 687 into our formula, we get:

(80 + 687)/2 = 383.5

Thus, the number halfway between 80 and 687 is 383.5.

To check that our answer is correct, we subtract 80 from 383.5 and subtract 383.5 from 687 and compare the two numbers:

383.5 - 80 = 303.5
687 - 383.5 = 303.5

As you can see, the halfway number is 303.5 higher than 80 and 303.5 lower than 687. Therefore, our halfway between answer of 383.5 above is correct.
