Halfway Between 12 and 899

When you ask "What number is halfway between 12 and 899?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=12 and Y=899.

Halfway Between Line

To find the number halfway between 12 and 899, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 12 and 899 into our formula, we get:

(12 + 899)/2 = 455.5

Thus, the number halfway between 12 and 899 is 455.5.

To check that our answer is correct, we subtract 12 from 455.5 and subtract 455.5 from 899 and compare the two numbers:

455.5 - 12 = 443.5
899 - 455.5 = 443.5

As you can see, the halfway number is 443.5 higher than 12 and 443.5 lower than 899. Therefore, our halfway between answer of 455.5 above is correct.
