Halfway Between 50 and 815

When you ask "What number is halfway between 50 and 815?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=50 and Y=815.

Halfway Between Line

To find the number halfway between 50 and 815, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 50 and 815 into our formula, we get:

(50 + 815)/2 = 432.5

Thus, the number halfway between 50 and 815 is 432.5.

To check that our answer is correct, we subtract 50 from 432.5 and subtract 432.5 from 815 and compare the two numbers:

432.5 - 50 = 382.5
815 - 432.5 = 382.5

As you can see, the halfway number is 382.5 higher than 50 and 382.5 lower than 815. Therefore, our halfway between answer of 432.5 above is correct.
