Halfway Between 27 and 488

When you ask "What number is halfway between 27 and 488?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=27 and Y=488.

Halfway Between Line

To find the number halfway between 27 and 488, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 27 and 488 into our formula, we get:

(27 + 488)/2 = 257.5

Thus, the number halfway between 27 and 488 is 257.5.

To check that our answer is correct, we subtract 27 from 257.5 and subtract 257.5 from 488 and compare the two numbers:

257.5 - 27 = 230.5
488 - 257.5 = 230.5

As you can see, the halfway number is 230.5 higher than 27 and 230.5 lower than 488. Therefore, our halfway between answer of 257.5 above is correct.
