Halfway Between 4 and 137

When you ask "What number is halfway between 4 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=4 and Y=137.

Halfway Between Line

To find the number halfway between 4 and 137, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 137 into our formula, we get:

(4 + 137)/2 = 70.5

Thus, the number halfway between 4 and 137 is 70.5.

To check that our answer is correct, we subtract 4 from 70.5 and subtract 70.5 from 137 and compare the two numbers:

70.5 - 4 = 66.5
137 - 70.5 = 66.5

As you can see, the halfway number is 66.5 higher than 4 and 66.5 lower than 137. Therefore, our halfway between answer of 70.5 above is correct.
