Halfway Between 100 and 808

When you ask "What number is halfway between 100 and 808?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=100 and Y=808.

Halfway Between Line

To find the number halfway between 100 and 808, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 808 into our formula, we get:

(100 + 808)/2 = 454

Thus, the number halfway between 100 and 808 is 454.

To check that our answer is correct, we subtract 100 from 454 and subtract 454 from 808 and compare the two numbers:

454 - 100 = 354
808 - 454 = 354

As you can see, the halfway number is 354 higher than 100 and 354 lower than 808. Therefore, our halfway between answer of 454 above is correct.
