Halfway Between 4 and 42

When you ask "What number is halfway between 4 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=4 and Y=42.

Halfway Between Line

To find the number halfway between 4 and 42, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 42 into our formula, we get:

(4 + 42)/2 = 23

Thus, the number halfway between 4 and 42 is 23.

To check that our answer is correct, we subtract 4 from 23 and subtract 23 from 42 and compare the two numbers:

23 - 4 = 19
42 - 23 = 19

As you can see, the halfway number is 19 higher than 4 and 19 lower than 42. Therefore, our halfway between answer of 23 above is correct.
