Halfway Between 15 and 126

When you ask "What number is halfway between 15 and 126?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=15 and Y=126.

Halfway Between Line

To find the number halfway between 15 and 126, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 126 into our formula, we get:

(15 + 126)/2 = 70.5

Thus, the number halfway between 15 and 126 is 70.5.

To check that our answer is correct, we subtract 15 from 70.5 and subtract 70.5 from 126 and compare the two numbers:

70.5 - 15 = 55.5
126 - 70.5 = 55.5

As you can see, the halfway number is 55.5 higher than 15 and 55.5 lower than 126. Therefore, our halfway between answer of 70.5 above is correct.
