Halfway Between 20 and 280

When you ask "What number is halfway between 20 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=20 and Y=280.

Halfway Between Line

To find the number halfway between 20 and 280, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 280 into our formula, we get:

(20 + 280)/2 = 150

Thus, the number halfway between 20 and 280 is 150.

To check that our answer is correct, we subtract 20 from 150 and subtract 150 from 280 and compare the two numbers:

150 - 20 = 130
280 - 150 = 130

As you can see, the halfway number is 130 higher than 20 and 130 lower than 280. Therefore, our halfway between answer of 150 above is correct.
