Halfway Between 90 and 280

When you ask "What number is halfway between 90 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=90 and Y=280.

Halfway Between Line

To find the number halfway between 90 and 280, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 280 into our formula, we get:

(90 + 280)/2 = 185

Thus, the number halfway between 90 and 280 is 185.

To check that our answer is correct, we subtract 90 from 185 and subtract 185 from 280 and compare the two numbers:

185 - 90 = 95
280 - 185 = 95

As you can see, the halfway number is 95 higher than 90 and 95 lower than 280. Therefore, our halfway between answer of 185 above is correct.
