Halfway Between 66 and 172

When you ask "What number is halfway between 66 and 172?" 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=172.

Halfway Between Line

To find the number halfway between 66 and 172, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 172 into our formula, we get:

(66 + 172)/2 = 119

Thus, the number halfway between 66 and 172 is 119.

To check that our answer is correct, we subtract 66 from 119 and subtract 119 from 172 and compare the two numbers:

119 - 66 = 53
172 - 119 = 53

As you can see, the halfway number is 53 higher than 66 and 53 lower than 172. Therefore, our halfway between answer of 119 above is correct.
