Halfway Between 45 and 137

When you ask "What number is halfway between 45 and 137?" 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=137.

Halfway Between Line

To find the number halfway between 45 and 137, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 137 into our formula, we get:

(45 + 137)/2 = 91

Thus, the number halfway between 45 and 137 is 91.

To check that our answer is correct, we subtract 45 from 91 and subtract 91 from 137 and compare the two numbers:

91 - 45 = 46
137 - 91 = 46

As you can see, the halfway number is 46 higher than 45 and 46 lower than 137. Therefore, our halfway between answer of 91 above is correct.
