Halfway Between 100 and 828

When you ask "What number is halfway between 100 and 828?" 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=828.

Halfway Between Line

To find the number halfway between 100 and 828, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 828 into our formula, we get:

(100 + 828)/2 = 464

Thus, the number halfway between 100 and 828 is 464.

To check that our answer is correct, we subtract 100 from 464 and subtract 464 from 828 and compare the two numbers:

464 - 100 = 364
828 - 464 = 364

As you can see, the halfway number is 364 higher than 100 and 364 lower than 828. Therefore, our halfway between answer of 464 above is correct.
