Halfway Between 10 and 280

When you ask "What number is halfway between 10 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=10 and Y=280.

Halfway Between Line

To find the number halfway between 10 and 280, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 10 and 280 into our formula, we get:

(10 + 280)/2 = 145

Thus, the number halfway between 10 and 280 is 145.

To check that our answer is correct, we subtract 10 from 145 and subtract 145 from 280 and compare the two numbers:

145 - 10 = 135
280 - 145 = 135

As you can see, the halfway number is 135 higher than 10 and 135 lower than 280. Therefore, our halfway between answer of 145 above is correct.
