Halfway Between 80 and 277

When you ask "What number is halfway between 80 and 277?" 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=277.

Halfway Between Line

To find the number halfway between 80 and 277, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 277 into our formula, we get:

(80 + 277)/2 = 178.5

Thus, the number halfway between 80 and 277 is 178.5.

To check that our answer is correct, we subtract 80 from 178.5 and subtract 178.5 from 277 and compare the two numbers:

178.5 - 80 = 98.5
277 - 178.5 = 98.5

As you can see, the halfway number is 98.5 higher than 80 and 98.5 lower than 277. Therefore, our halfway between answer of 178.5 above is correct.
