Halfway Between 64 and 66

When you ask "What number is halfway between 64 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=64 and Y=66.

Halfway Between Line

To find the number halfway between 64 and 66, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 64 and 66 into our formula, we get:

(64 + 66)/2 = 65

Thus, the number halfway between 64 and 66 is 65.

To check that our answer is correct, we subtract 64 from 65 and subtract 65 from 66 and compare the two numbers:

65 - 64 = 1
66 - 65 = 1

As you can see, the halfway number is 1 higher than 64 and 1 lower than 66. Therefore, our halfway between answer of 65 above is correct.
