Halfway Between 80 and 553

When you ask "What number is halfway between 80 and 553?" 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=553.

Halfway Between Line

To find the number halfway between 80 and 553, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 553 into our formula, we get:

(80 + 553)/2 = 316.5

Thus, the number halfway between 80 and 553 is 316.5.

To check that our answer is correct, we subtract 80 from 316.5 and subtract 316.5 from 553 and compare the two numbers:

316.5 - 80 = 236.5
553 - 316.5 = 236.5

As you can see, the halfway number is 236.5 higher than 80 and 236.5 lower than 553. Therefore, our halfway between answer of 316.5 above is correct.
