Halfway Between 80 and 810

When you ask "What number is halfway between 80 and 810?" 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=810.

Halfway Between Line

To find the number halfway between 80 and 810, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 810 into our formula, we get:

(80 + 810)/2 = 445

Thus, the number halfway between 80 and 810 is 445.

To check that our answer is correct, we subtract 80 from 445 and subtract 445 from 810 and compare the two numbers:

445 - 80 = 365
810 - 445 = 365

As you can see, the halfway number is 365 higher than 80 and 365 lower than 810. Therefore, our halfway between answer of 445 above is correct.
