Halfway Between 78 and 456

When you ask "What number is halfway between 78 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=78 and Y=456.

Halfway Between Line

To find the number halfway between 78 and 456, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 456 into our formula, we get:

(78 + 456)/2 = 267

Thus, the number halfway between 78 and 456 is 267.

To check that our answer is correct, we subtract 78 from 267 and subtract 267 from 456 and compare the two numbers:

267 - 78 = 189
456 - 267 = 189

As you can see, the halfway number is 189 higher than 78 and 189 lower than 456. Therefore, our halfway between answer of 267 above is correct.
