Halfway Between 31 and 1000

When you ask "What number is halfway between 31 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=31 and Y=1000.

Halfway Between Line

To find the number halfway between 31 and 1000, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 31 and 1000 into our formula, we get:

(31 + 1000)/2 = 515.5

Thus, the number halfway between 31 and 1000 is 515.5.

To check that our answer is correct, we subtract 31 from 515.5 and subtract 515.5 from 1000 and compare the two numbers:

515.5 - 31 = 484.5
1000 - 515.5 = 484.5

As you can see, the halfway number is 484.5 higher than 31 and 484.5 lower than 1000. Therefore, our halfway between answer of 515.5 above is correct.
