Halfway Between 20 and 64

When you ask "What number is halfway between 20 and 64?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=20 and Y=64.

Halfway Between Line

To find the number halfway between 20 and 64, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 64 into our formula, we get:

(20 + 64)/2 = 42

Thus, the number halfway between 20 and 64 is 42.

To check that our answer is correct, we subtract 20 from 42 and subtract 42 from 64 and compare the two numbers:

42 - 20 = 22
64 - 42 = 22

As you can see, the halfway number is 22 higher than 20 and 22 lower than 64. Therefore, our halfway between answer of 42 above is correct.
