Halfway Between 66 and 280

When you ask "What number is halfway between 66 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=66 and Y=280.

Halfway Between Line

To find the number halfway between 66 and 280, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 280 into our formula, we get:

(66 + 280)/2 = 173

Thus, the number halfway between 66 and 280 is 173.

To check that our answer is correct, we subtract 66 from 173 and subtract 173 from 280 and compare the two numbers:

173 - 66 = 107
280 - 173 = 107

As you can see, the halfway number is 107 higher than 66 and 107 lower than 280. Therefore, our halfway between answer of 173 above is correct.
