Halfway Between 30 and 899

When you ask "What number is halfway between 30 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=30 and Y=899.

Halfway Between Line

To find the number halfway between 30 and 899, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 899 into our formula, we get:

(30 + 899)/2 = 464.5

Thus, the number halfway between 30 and 899 is 464.5.

To check that our answer is correct, we subtract 30 from 464.5 and subtract 464.5 from 899 and compare the two numbers:

464.5 - 30 = 434.5
899 - 464.5 = 434.5

As you can see, the halfway number is 434.5 higher than 30 and 434.5 lower than 899. Therefore, our halfway between answer of 464.5 above is correct.
