Halfway Between 65 and 815

When you ask "What number is halfway between 65 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=65 and Y=815.

Halfway Between Line

To find the number halfway between 65 and 815, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 65 and 815 into our formula, we get:

(65 + 815)/2 = 440

Thus, the number halfway between 65 and 815 is 440.

To check that our answer is correct, we subtract 65 from 440 and subtract 440 from 815 and compare the two numbers:

440 - 65 = 375
815 - 440 = 375

As you can see, the halfway number is 375 higher than 65 and 375 lower than 815. Therefore, our halfway between answer of 440 above is correct.
