Halfway Between 72 and 172

When you ask "What number is halfway between 72 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=72 and Y=172.

Halfway Between Line

To find the number halfway between 72 and 172, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 72 and 172 into our formula, we get:

(72 + 172)/2 = 122

Thus, the number halfway between 72 and 172 is 122.

To check that our answer is correct, we subtract 72 from 122 and subtract 122 from 172 and compare the two numbers:

122 - 72 = 50
172 - 122 = 50

As you can see, the halfway number is 50 higher than 72 and 50 lower than 172. Therefore, our halfway between answer of 122 above is correct.
