Halfway Between 66 and 75

When you ask "What number is halfway between 66 and 75?" 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=75.

Halfway Between Line

To find the number halfway between 66 and 75, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 75 into our formula, we get:

(66 + 75)/2 = 70.5

Thus, the number halfway between 66 and 75 is 70.5.

To check that our answer is correct, we subtract 66 from 70.5 and subtract 70.5 from 75 and compare the two numbers:

70.5 - 66 = 4.5
75 - 70.5 = 4.5

As you can see, the halfway number is 4.5 higher than 66 and 4.5 lower than 75. Therefore, our halfway between answer of 70.5 above is correct.
