Halfway Between 78 and 280

When you ask "What number is halfway between 78 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=78 and Y=280.

Halfway Between Line

To find the number halfway between 78 and 280, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 280 into our formula, we get:

(78 + 280)/2 = 179

Thus, the number halfway between 78 and 280 is 179.

To check that our answer is correct, we subtract 78 from 179 and subtract 179 from 280 and compare the two numbers:

179 - 78 = 101
280 - 179 = 101

As you can see, the halfway number is 101 higher than 78 and 101 lower than 280. Therefore, our halfway between answer of 179 above is correct.
