Halfway Between 100 and 172

When you ask "What number is halfway between 100 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=100 and Y=172.

Halfway Between Line

To find the number halfway between 100 and 172, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 172 into our formula, we get:

(100 + 172)/2 = 136

Thus, the number halfway between 100 and 172 is 136.

To check that our answer is correct, we subtract 100 from 136 and subtract 136 from 172 and compare the two numbers:

136 - 100 = 36
172 - 136 = 36

As you can see, the halfway number is 36 higher than 100 and 36 lower than 172. Therefore, our halfway between answer of 136 above is correct.
