Halfway Between 1 and 280

When you ask "What number is halfway between 1 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=1 and Y=280.

Halfway Between Line

To find the number halfway between 1 and 280, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 280 into our formula, we get:

(1 + 280)/2 = 140.5

Thus, the number halfway between 1 and 280 is 140.5.

To check that our answer is correct, we subtract 1 from 140.5 and subtract 140.5 from 280 and compare the two numbers:

140.5 - 1 = 139.5
280 - 140.5 = 139.5

As you can see, the halfway number is 139.5 higher than 1 and 139.5 lower than 280. Therefore, our halfway between answer of 140.5 above is correct.
