Halfway Between 31 and 825

When you ask "What number is halfway between 31 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=31 and Y=825.

Halfway Between Line

To find the number halfway between 31 and 825, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 31 and 825 into our formula, we get:

(31 + 825)/2 = 428

Thus, the number halfway between 31 and 825 is 428.

To check that our answer is correct, we subtract 31 from 428 and subtract 428 from 825 and compare the two numbers:

428 - 31 = 397
825 - 428 = 397

As you can see, the halfway number is 397 higher than 31 and 397 lower than 825. Therefore, our halfway between answer of 428 above is correct.
