Halfway Between 30 and 825

When you ask "What number is halfway between 30 and 825?" 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=825.

Halfway Between Line

To find the number halfway between 30 and 825, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 825 into our formula, we get:

(30 + 825)/2 = 427.5

Thus, the number halfway between 30 and 825 is 427.5.

To check that our answer is correct, we subtract 30 from 427.5 and subtract 427.5 from 825 and compare the two numbers:

427.5 - 30 = 397.5
825 - 427.5 = 397.5

As you can see, the halfway number is 397.5 higher than 30 and 397.5 lower than 825. Therefore, our halfway between answer of 427.5 above is correct.
