Halfway Between 67 and 645

When you ask "What number is halfway between 67 and 645?" 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=645.

Halfway Between Line

To find the number halfway between 67 and 645, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 67 and 645 into our formula, we get:

(67 + 645)/2 = 356

Thus, the number halfway between 67 and 645 is 356.

To check that our answer is correct, we subtract 67 from 356 and subtract 356 from 645 and compare the two numbers:

356 - 67 = 289
645 - 356 = 289

As you can see, the halfway number is 289 higher than 67 and 289 lower than 645. Therefore, our halfway between answer of 356 above is correct.
