Halfway Between 9 and 137

When you ask "What number is halfway between 9 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=9 and Y=137.

Halfway Between Line

To find the number halfway between 9 and 137, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 9 and 137 into our formula, we get:

(9 + 137)/2 = 73

Thus, the number halfway between 9 and 137 is 73.

To check that our answer is correct, we subtract 9 from 73 and subtract 73 from 137 and compare the two numbers:

73 - 9 = 64
137 - 73 = 64

As you can see, the halfway number is 64 higher than 9 and 64 lower than 137. Therefore, our halfway between answer of 73 above is correct.
