Halfway Between 78 and 306

When you ask "What number is halfway between 78 and 306?" 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=306.

Halfway Between Line

To find the number halfway between 78 and 306, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 306 into our formula, we get:

(78 + 306)/2 = 192

Thus, the number halfway between 78 and 306 is 192.

To check that our answer is correct, we subtract 78 from 192 and subtract 192 from 306 and compare the two numbers:

192 - 78 = 114
306 - 192 = 114

As you can see, the halfway number is 114 higher than 78 and 114 lower than 306. Therefore, our halfway between answer of 192 above is correct.
