Halfway Between 78 and 247

When you ask "What number is halfway between 78 and 247?" 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=247.

Halfway Between Line

To find the number halfway between 78 and 247, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 247 into our formula, we get:

(78 + 247)/2 = 162.5

Thus, the number halfway between 78 and 247 is 162.5.

To check that our answer is correct, we subtract 78 from 162.5 and subtract 162.5 from 247 and compare the two numbers:

162.5 - 78 = 84.5
247 - 162.5 = 84.5

As you can see, the halfway number is 84.5 higher than 78 and 84.5 lower than 247. Therefore, our halfway between answer of 162.5 above is correct.
