Halfway Between 1 and 900

When you ask "What number is halfway between 1 and 900?" 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=900.

Halfway Between Line

To find the number halfway between 1 and 900, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 900 into our formula, we get:

(1 + 900)/2 = 450.5

Thus, the number halfway between 1 and 900 is 450.5.

To check that our answer is correct, we subtract 1 from 450.5 and subtract 450.5 from 900 and compare the two numbers:

450.5 - 1 = 449.5
900 - 450.5 = 449.5

As you can see, the halfway number is 449.5 higher than 1 and 449.5 lower than 900. Therefore, our halfway between answer of 450.5 above is correct.
