Halfway Between 66 and 67

When you ask "What number is halfway between 66 and 67?" 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=67.

Halfway Between Line

To find the number halfway between 66 and 67, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 67 into our formula, we get:

(66 + 67)/2 = 66.5

Thus, the number halfway between 66 and 67 is 66.5.

To check that our answer is correct, we subtract 66 from 66.5 and subtract 66.5 from 67 and compare the two numbers:

66.5 - 66 = 0.5
67 - 66.5 = 0.5

As you can see, the halfway number is 0.5 higher than 66 and 0.5 lower than 67. Therefore, our halfway between answer of 66.5 above is correct.
