Halfway Between 67 and 665

When you ask "What number is halfway between 67 and 665?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=67 and Y=665.

Halfway Between Line

To find the number halfway between 67 and 665, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 67 and 665 into our formula, we get:

(67 + 665)/2 = 366

Thus, the number halfway between 67 and 665 is 366.

To check that our answer is correct, we subtract 67 from 366 and subtract 366 from 665 and compare the two numbers:

366 - 67 = 299
665 - 366 = 299

As you can see, the halfway number is 299 higher than 67 and 299 lower than 665. Therefore, our halfway between answer of 366 above is correct.
