Halfway Between 5 and 800

When you ask "What number is halfway between 5 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=5 and Y=800.

Halfway Between Line

To find the number halfway between 5 and 800, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 5 and 800 into our formula, we get:

(5 + 800)/2 = 402.5

Thus, the number halfway between 5 and 800 is 402.5.

To check that our answer is correct, we subtract 5 from 402.5 and subtract 402.5 from 800 and compare the two numbers:

402.5 - 5 = 397.5
800 - 402.5 = 397.5

As you can see, the halfway number is 397.5 higher than 5 and 397.5 lower than 800. Therefore, our halfway between answer of 402.5 above is correct.
