Halfway Between 78 and 203

When you ask "What number is halfway between 78 and 203?" 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=203.

Halfway Between Line

To find the number halfway between 78 and 203, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 203 into our formula, we get:

(78 + 203)/2 = 140.5

Thus, the number halfway between 78 and 203 is 140.5.

To check that our answer is correct, we subtract 78 from 140.5 and subtract 140.5 from 203 and compare the two numbers:

140.5 - 78 = 62.5
203 - 140.5 = 62.5

As you can see, the halfway number is 62.5 higher than 78 and 62.5 lower than 203. Therefore, our halfway between answer of 140.5 above is correct.
