Halfway Between 78 and 354

When you ask "What number is halfway between 78 and 354?" 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=354.

Halfway Between Line

To find the number halfway between 78 and 354, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 354 into our formula, we get:

(78 + 354)/2 = 216

Thus, the number halfway between 78 and 354 is 216.

To check that our answer is correct, we subtract 78 from 216 and subtract 216 from 354 and compare the two numbers:

216 - 78 = 138
354 - 216 = 138

As you can see, the halfway number is 138 higher than 78 and 138 lower than 354. Therefore, our halfway between answer of 216 above is correct.
