Halfway Between 78 and 308

When you ask "What number is halfway between 78 and 308?" 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=308.

Halfway Between Line

To find the number halfway between 78 and 308, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 308 into our formula, we get:

(78 + 308)/2 = 193

Thus, the number halfway between 78 and 308 is 193.

To check that our answer is correct, we subtract 78 from 193 and subtract 193 from 308 and compare the two numbers:

193 - 78 = 115
308 - 193 = 115

As you can see, the halfway number is 115 higher than 78 and 115 lower than 308. Therefore, our halfway between answer of 193 above is correct.
