Halfway Between 4 and 66

When you ask "What number is halfway between 4 and 66?" 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=66.

Halfway Between Line

To find the number halfway between 4 and 66, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 66 into our formula, we get:

(4 + 66)/2 = 35

Thus, the number halfway between 4 and 66 is 35.

To check that our answer is correct, we subtract 4 from 35 and subtract 35 from 66 and compare the two numbers:

35 - 4 = 31
66 - 35 = 31

As you can see, the halfway number is 31 higher than 4 and 31 lower than 66. Therefore, our halfway between answer of 35 above is correct.
