Halfway Between 78 and 166

When you ask "What number is halfway between 78 and 166?" 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=166.

Halfway Between Line

To find the number halfway between 78 and 166, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 78 and 166 into our formula, we get:

(78 + 166)/2 = 122

Thus, the number halfway between 78 and 166 is 122.

To check that our answer is correct, we subtract 78 from 122 and subtract 122 from 166 and compare the two numbers:

122 - 78 = 44
166 - 122 = 44

As you can see, the halfway number is 44 higher than 78 and 44 lower than 166. Therefore, our halfway between answer of 122 above is correct.
