Halfway Between 80 and 275

When you ask "What number is halfway between 80 and 275?" 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=275.

Halfway Between Line

To find the number halfway between 80 and 275, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 275 into our formula, we get:

(80 + 275)/2 = 177.5

Thus, the number halfway between 80 and 275 is 177.5.

To check that our answer is correct, we subtract 80 from 177.5 and subtract 177.5 from 275 and compare the two numbers:

177.5 - 80 = 97.5
275 - 177.5 = 97.5

As you can see, the halfway number is 97.5 higher than 80 and 97.5 lower than 275. Therefore, our halfway between answer of 177.5 above is correct.
