Halfway Between 80 and 623

When you ask "What number is halfway between 80 and 623?" 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=623.

Halfway Between Line

To find the number halfway between 80 and 623, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 623 into our formula, we get:

(80 + 623)/2 = 351.5

Thus, the number halfway between 80 and 623 is 351.5.

To check that our answer is correct, we subtract 80 from 351.5 and subtract 351.5 from 623 and compare the two numbers:

351.5 - 80 = 271.5
623 - 351.5 = 271.5

As you can see, the halfway number is 271.5 higher than 80 and 271.5 lower than 623. Therefore, our halfway between answer of 351.5 above is correct.
