Halfway Between 87 and 137

When you ask "What number is halfway between 87 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=87 and Y=137.

Halfway Between Line

To find the number halfway between 87 and 137, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 87 and 137 into our formula, we get:

(87 + 137)/2 = 112

Thus, the number halfway between 87 and 137 is 112.

To check that our answer is correct, we subtract 87 from 112 and subtract 112 from 137 and compare the two numbers:

112 - 87 = 25
137 - 112 = 25

As you can see, the halfway number is 25 higher than 87 and 25 lower than 137. Therefore, our halfway between answer of 112 above is correct.
