Halfway Between 80 and 820

When you ask "What number is halfway between 80 and 820?" 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=820.

Halfway Between Line

To find the number halfway between 80 and 820, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 820 into our formula, we get:

(80 + 820)/2 = 450

Thus, the number halfway between 80 and 820 is 450.

To check that our answer is correct, we subtract 80 from 450 and subtract 450 from 820 and compare the two numbers:

450 - 80 = 370
820 - 450 = 370

As you can see, the halfway number is 370 higher than 80 and 370 lower than 820. Therefore, our halfway between answer of 450 above is correct.
