Halfway Between 66 and 137

When you ask "What number is halfway between 66 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=66 and Y=137.

Halfway Between Line

To find the number halfway between 66 and 137, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 137 into our formula, we get:

(66 + 137)/2 = 101.5

Thus, the number halfway between 66 and 137 is 101.5.

To check that our answer is correct, we subtract 66 from 101.5 and subtract 101.5 from 137 and compare the two numbers:

101.5 - 66 = 35.5
137 - 101.5 = 35.5

As you can see, the halfway number is 35.5 higher than 66 and 35.5 lower than 137. Therefore, our halfway between answer of 101.5 above is correct.
