Halfway Between 4 and 90

When you ask "What number is halfway between 4 and 90?" 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=90.

Halfway Between Line

To find the number halfway between 4 and 90, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 90 into our formula, we get:

(4 + 90)/2 = 47

Thus, the number halfway between 4 and 90 is 47.

To check that our answer is correct, we subtract 4 from 47 and subtract 47 from 90 and compare the two numbers:

47 - 4 = 43
90 - 47 = 43

As you can see, the halfway number is 43 higher than 4 and 43 lower than 90. Therefore, our halfway between answer of 47 above is correct.
