Halfway Between 43 and 815

When you ask "What number is halfway between 43 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=43 and Y=815.

Halfway Between Line

To find the number halfway between 43 and 815, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 43 and 815 into our formula, we get:

(43 + 815)/2 = 429

Thus, the number halfway between 43 and 815 is 429.

To check that our answer is correct, we subtract 43 from 429 and subtract 429 from 815 and compare the two numbers:

429 - 43 = 386
815 - 429 = 386

As you can see, the halfway number is 386 higher than 43 and 386 lower than 815. Therefore, our halfway between answer of 429 above is correct.
