Halfway Between 100 and 854

When you ask "What number is halfway between 100 and 854?" 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=854.

Halfway Between Line

To find the number halfway between 100 and 854, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 854 into our formula, we get:

(100 + 854)/2 = 477

Thus, the number halfway between 100 and 854 is 477.

To check that our answer is correct, we subtract 100 from 477 and subtract 477 from 854 and compare the two numbers:

477 - 100 = 377
854 - 477 = 377

As you can see, the halfway number is 377 higher than 100 and 377 lower than 854. Therefore, our halfway between answer of 477 above is correct.
