Halfway Between 66 and 88

When you ask "What number is halfway between 66 and 88?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=66 and Y=88.

Halfway Between Line

To find the number halfway between 66 and 88, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 88 into our formula, we get:

(66 + 88)/2 = 77

Thus, the number halfway between 66 and 88 is 77.

To check that our answer is correct, we subtract 66 from 77 and subtract 77 from 88 and compare the two numbers:

77 - 66 = 11
88 - 77 = 11

As you can see, the halfway number is 11 higher than 66 and 11 lower than 88. Therefore, our halfway between answer of 77 above is correct.
