Halfway Between 1 and 1000

When you ask "What number is halfway between 1 and 1000?" 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=1000.

Halfway Between Line

To find the number halfway between 1 and 1000, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 1000 into our formula, we get:

(1 + 1000)/2 = 500.5

Thus, the number halfway between 1 and 1000 is 500.5.

To check that our answer is correct, we subtract 1 from 500.5 and subtract 500.5 from 1000 and compare the two numbers:

500.5 - 1 = 499.5
1000 - 500.5 = 499.5

As you can see, the halfway number is 499.5 higher than 1 and 499.5 lower than 1000. Therefore, our halfway between answer of 500.5 above is correct.
