Halfway Between 18 and 488

When you ask "What number is halfway between 18 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=18 and Y=488.

Halfway Between Line

To find the number halfway between 18 and 488, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 18 and 488 into our formula, we get:

(18 + 488)/2 = 253

Thus, the number halfway between 18 and 488 is 253.

To check that our answer is correct, we subtract 18 from 253 and subtract 253 from 488 and compare the two numbers:

253 - 18 = 235
488 - 253 = 235

As you can see, the halfway number is 235 higher than 18 and 235 lower than 488. Therefore, our halfway between answer of 253 above is correct.
