Halfway Between 78 and 545

When you ask "What number is halfway between 78 and 545?" 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=545.

Halfway Between Line

To find the number halfway between 78 and 545, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 545 into our formula, we get:

(78 + 545)/2 = 311.5

Thus, the number halfway between 78 and 545 is 311.5.

To check that our answer is correct, we subtract 78 from 311.5 and subtract 311.5 from 545 and compare the two numbers:

311.5 - 78 = 233.5
545 - 311.5 = 233.5

As you can see, the halfway number is 233.5 higher than 78 and 233.5 lower than 545. Therefore, our halfway between answer of 311.5 above is correct.
