Halfway Between 80 and 644

When you ask "What number is halfway between 80 and 644?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=80 and Y=644.

Halfway Between Line

To find the number halfway between 80 and 644, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 644 into our formula, we get:

(80 + 644)/2 = 362

Thus, the number halfway between 80 and 644 is 362.

To check that our answer is correct, we subtract 80 from 362 and subtract 362 from 644 and compare the two numbers:

362 - 80 = 282
644 - 362 = 282

As you can see, the halfway number is 282 higher than 80 and 282 lower than 644. Therefore, our halfway between answer of 362 above is correct.
