Halfway Between 90 and 137

When you ask "What number is halfway between 90 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=90 and Y=137.

Halfway Between Line

To find the number halfway between 90 and 137, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 90 and 137 into our formula, we get:

(90 + 137)/2 = 113.5

Thus, the number halfway between 90 and 137 is 113.5.

To check that our answer is correct, we subtract 90 from 113.5 and subtract 113.5 from 137 and compare the two numbers:

113.5 - 90 = 23.5
137 - 113.5 = 23.5

As you can see, the halfway number is 23.5 higher than 90 and 23.5 lower than 137. Therefore, our halfway between answer of 113.5 above is correct.
