Halfway Between 1 and 800

When you ask "What number is halfway between 1 and 800?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=1 and Y=800.

Halfway Between Line

To find the number halfway between 1 and 800, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 800 into our formula, we get:

(1 + 800)/2 = 400.5

Thus, the number halfway between 1 and 800 is 400.5.

To check that our answer is correct, we subtract 1 from 400.5 and subtract 400.5 from 800 and compare the two numbers:

400.5 - 1 = 399.5
800 - 400.5 = 399.5

As you can see, the halfway number is 399.5 higher than 1 and 399.5 lower than 800. Therefore, our halfway between answer of 400.5 above is correct.
