Halfway Between 78 and 208

When you ask "What number is halfway between 78 and 208?" 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=208.

Halfway Between Line

To find the number halfway between 78 and 208, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 208 into our formula, we get:

(78 + 208)/2 = 143

Thus, the number halfway between 78 and 208 is 143.

To check that our answer is correct, we subtract 78 from 143 and subtract 143 from 208 and compare the two numbers:

143 - 78 = 65
208 - 143 = 65

As you can see, the halfway number is 65 higher than 78 and 65 lower than 208. Therefore, our halfway between answer of 143 above is correct.
