Halfway Between 100 and 456

When you ask "What number is halfway between 100 and 456?" 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=456.

Halfway Between Line

To find the number halfway between 100 and 456, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 456 into our formula, we get:

(100 + 456)/2 = 278

Thus, the number halfway between 100 and 456 is 278.

To check that our answer is correct, we subtract 100 from 278 and subtract 278 from 456 and compare the two numbers:

278 - 100 = 178
456 - 278 = 178

As you can see, the halfway number is 178 higher than 100 and 178 lower than 456. Therefore, our halfway between answer of 278 above is correct.
