Halfway Between 66 and 178

When you ask "What number is halfway between 66 and 178?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=66 and Y=178.

Halfway Between Line

To find the number halfway between 66 and 178, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 178 into our formula, we get:

(66 + 178)/2 = 122

Thus, the number halfway between 66 and 178 is 122.

To check that our answer is correct, we subtract 66 from 122 and subtract 122 from 178 and compare the two numbers:

122 - 66 = 56
178 - 122 = 56

As you can see, the halfway number is 56 higher than 66 and 56 lower than 178. Therefore, our halfway between answer of 122 above is correct.
