Halfway Between 100 and 823

When you ask "What number is halfway between 100 and 823?" 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=823.

Halfway Between Line

To find the number halfway between 100 and 823, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 823 into our formula, we get:

(100 + 823)/2 = 461.5

Thus, the number halfway between 100 and 823 is 461.5.

To check that our answer is correct, we subtract 100 from 461.5 and subtract 461.5 from 823 and compare the two numbers:

461.5 - 100 = 361.5
823 - 461.5 = 361.5

As you can see, the halfway number is 361.5 higher than 100 and 361.5 lower than 823. Therefore, our halfway between answer of 461.5 above is correct.
