Halfway Between 61 and 815

When you ask "What number is halfway between 61 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=61 and Y=815.

Halfway Between Line

To find the number halfway between 61 and 815, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 61 and 815 into our formula, we get:

(61 + 815)/2 = 438

Thus, the number halfway between 61 and 815 is 438.

To check that our answer is correct, we subtract 61 from 438 and subtract 438 from 815 and compare the two numbers:

438 - 61 = 377
815 - 438 = 377

As you can see, the halfway number is 377 higher than 61 and 377 lower than 815. Therefore, our halfway between answer of 438 above is correct.
