Halfway Between 4 and 280

When you ask "What number is halfway between 4 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=4 and Y=280.

Halfway Between Line

To find the number halfway between 4 and 280, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 280 into our formula, we get:

(4 + 280)/2 = 142

Thus, the number halfway between 4 and 280 is 142.

To check that our answer is correct, we subtract 4 from 142 and subtract 142 from 280 and compare the two numbers:

142 - 4 = 138
280 - 142 = 138

As you can see, the halfway number is 138 higher than 4 and 138 lower than 280. Therefore, our halfway between answer of 142 above is correct.
