Halfway Between 30 and 42

When you ask "What number is halfway between 30 and 42?" 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=42.

Halfway Between Line

To find the number halfway between 30 and 42, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 42 into our formula, we get:

(30 + 42)/2 = 36

Thus, the number halfway between 30 and 42 is 36.

To check that our answer is correct, we subtract 30 from 36 and subtract 36 from 42 and compare the two numbers:

36 - 30 = 6
42 - 36 = 6

As you can see, the halfway number is 6 higher than 30 and 6 lower than 42. Therefore, our halfway between answer of 36 above is correct.
