Halfway Between 31 and 137

When you ask "What number is halfway between 31 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=31 and Y=137.

Halfway Between Line

To find the number halfway between 31 and 137, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 31 and 137 into our formula, we get:

(31 + 137)/2 = 84

Thus, the number halfway between 31 and 137 is 84.

To check that our answer is correct, we subtract 31 from 84 and subtract 84 from 137 and compare the two numbers:

84 - 31 = 53
137 - 84 = 53

As you can see, the halfway number is 53 higher than 31 and 53 lower than 137. Therefore, our halfway between answer of 84 above is correct.
