Halfway Between 80 and 869

When you ask "What number is halfway between 80 and 869?" 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=869.

Halfway Between Line

To find the number halfway between 80 and 869, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 869 into our formula, we get:

(80 + 869)/2 = 474.5

Thus, the number halfway between 80 and 869 is 474.5.

To check that our answer is correct, we subtract 80 from 474.5 and subtract 474.5 from 869 and compare the two numbers:

474.5 - 80 = 394.5
869 - 474.5 = 394.5

As you can see, the halfway number is 394.5 higher than 80 and 394.5 lower than 869. Therefore, our halfway between answer of 474.5 above is correct.
