Halfway Between 78 and 408

When you ask "What number is halfway between 78 and 408?" 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=408.

Halfway Between Line

To find the number halfway between 78 and 408, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 408 into our formula, we get:

(78 + 408)/2 = 243

Thus, the number halfway between 78 and 408 is 243.

To check that our answer is correct, we subtract 78 from 243 and subtract 243 from 408 and compare the two numbers:

243 - 78 = 165
408 - 243 = 165

As you can see, the halfway number is 165 higher than 78 and 165 lower than 408. Therefore, our halfway between answer of 243 above is correct.
