Halfway Between 80 and 646

When you ask "What number is halfway between 80 and 646?" 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=646.

Halfway Between Line

To find the number halfway between 80 and 646, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 646 into our formula, we get:

(80 + 646)/2 = 363

Thus, the number halfway between 80 and 646 is 363.

To check that our answer is correct, we subtract 80 from 363 and subtract 363 from 646 and compare the two numbers:

363 - 80 = 283
646 - 363 = 283

As you can see, the halfway number is 283 higher than 80 and 283 lower than 646. Therefore, our halfway between answer of 363 above is correct.
