Halfway Between 30 and 178

When you ask "What number is halfway between 30 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=30 and Y=178.

Halfway Between Line

To find the number halfway between 30 and 178, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 178 into our formula, we get:

(30 + 178)/2 = 104

Thus, the number halfway between 30 and 178 is 104.

To check that our answer is correct, we subtract 30 from 104 and subtract 104 from 178 and compare the two numbers:

104 - 30 = 74
178 - 104 = 74

As you can see, the halfway number is 74 higher than 30 and 74 lower than 178. Therefore, our halfway between answer of 104 above is correct.
