Halfway Between 90 and 488

When you ask "What number is halfway between 90 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=90 and Y=488.

Halfway Between Line

To find the number halfway between 90 and 488, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 488 into our formula, we get:

(90 + 488)/2 = 289

Thus, the number halfway between 90 and 488 is 289.

To check that our answer is correct, we subtract 90 from 289 and subtract 289 from 488 and compare the two numbers:

289 - 90 = 199
488 - 289 = 199

As you can see, the halfway number is 199 higher than 90 and 199 lower than 488. Therefore, our halfway between answer of 289 above is correct.
