Halfway Between 80 and 649

When you ask "What number is halfway between 80 and 649?" 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=649.

Halfway Between Line

To find the number halfway between 80 and 649, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 649 into our formula, we get:

(80 + 649)/2 = 364.5

Thus, the number halfway between 80 and 649 is 364.5.

To check that our answer is correct, we subtract 80 from 364.5 and subtract 364.5 from 649 and compare the two numbers:

364.5 - 80 = 284.5
649 - 364.5 = 284.5

As you can see, the halfway number is 284.5 higher than 80 and 284.5 lower than 649. Therefore, our halfway between answer of 364.5 above is correct.
