When you ask "What number is halfway between 89 and 801?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=89 and Y=801.

To find the number halfway between 89 and 801, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 89 and 801 into our formula, we get:
(89 + 801)/2 = 445
Thus, the number halfway between 89 and 801 is 445.
To check that our answer is correct, we subtract 89 from 445 and subtract 445 from 801 and compare the two numbers:
445 - 89 = 356
801 - 445 = 356
As you can see, the halfway number is 356 higher than 89 and 356 lower than 801. Therefore, our halfway between answer of 445 above is correct.
