Halfway Between 78 and 319

When you ask "What number is halfway between 78 and 319?" 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=319.

Halfway Between Line

To find the number halfway between 78 and 319, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 319 into our formula, we get:

(78 + 319)/2 = 198.5

Thus, the number halfway between 78 and 319 is 198.5.

To check that our answer is correct, we subtract 78 from 198.5 and subtract 198.5 from 319 and compare the two numbers:

198.5 - 78 = 120.5
319 - 198.5 = 120.5

As you can see, the halfway number is 120.5 higher than 78 and 120.5 lower than 319. Therefore, our halfway between answer of 198.5 above is correct.
