Halfway Between 55 and 280

When you ask "What number is halfway between 55 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=55 and Y=280.

Halfway Between Line

To find the number halfway between 55 and 280, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 280 into our formula, we get:

(55 + 280)/2 = 167.5

Thus, the number halfway between 55 and 280 is 167.5.

To check that our answer is correct, we subtract 55 from 167.5 and subtract 167.5 from 280 and compare the two numbers:

167.5 - 55 = 112.5
280 - 167.5 = 112.5

As you can see, the halfway number is 112.5 higher than 55 and 112.5 lower than 280. Therefore, our halfway between answer of 167.5 above is correct.
