Halfway Between 77 and 280

When you ask "What number is halfway between 77 and 280?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=77 and Y=280.

Halfway Between Line

To find the number halfway between 77 and 280, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 77 and 280 into our formula, we get:

(77 + 280)/2 = 178.5

Thus, the number halfway between 77 and 280 is 178.5.

To check that our answer is correct, we subtract 77 from 178.5 and subtract 178.5 from 280 and compare the two numbers:

178.5 - 77 = 101.5
280 - 178.5 = 101.5

As you can see, the halfway number is 101.5 higher than 77 and 101.5 lower than 280. Therefore, our halfway between answer of 178.5 above is correct.
