Halfway Between 80 and 831

When you ask "What number is halfway between 80 and 831?" 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=831.

Halfway Between Line

To find the number halfway between 80 and 831, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 831 into our formula, we get:

(80 + 831)/2 = 455.5

Thus, the number halfway between 80 and 831 is 455.5.

To check that our answer is correct, we subtract 80 from 455.5 and subtract 455.5 from 831 and compare the two numbers:

455.5 - 80 = 375.5
831 - 455.5 = 375.5

As you can see, the halfway number is 375.5 higher than 80 and 375.5 lower than 831. Therefore, our halfway between answer of 455.5 above is correct.
