Halfway Between 45 and 189

When you ask "What number is halfway between 45 and 189?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=45 and Y=189.

Halfway Between Line

To find the number halfway between 45 and 189, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 189 into our formula, we get:

(45 + 189)/2 = 117

Thus, the number halfway between 45 and 189 is 117.

To check that our answer is correct, we subtract 45 from 117 and subtract 117 from 189 and compare the two numbers:

117 - 45 = 72
189 - 117 = 72

As you can see, the halfway number is 72 higher than 45 and 72 lower than 189. Therefore, our halfway between answer of 117 above is correct.
