Halfway Between 78 and 320

When you ask "What number is halfway between 78 and 320?" 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=320.

Halfway Between Line

To find the number halfway between 78 and 320, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 320 into our formula, we get:

(78 + 320)/2 = 199

Thus, the number halfway between 78 and 320 is 199.

To check that our answer is correct, we subtract 78 from 199 and subtract 199 from 320 and compare the two numbers:

199 - 78 = 121
320 - 199 = 121

As you can see, the halfway number is 121 higher than 78 and 121 lower than 320. Therefore, our halfway between answer of 199 above is correct.
