Halfway Between 15 and 159

When you ask "What number is halfway between 15 and 159?" 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=159.

Halfway Between Line

To find the number halfway between 15 and 159, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 159 into our formula, we get:

(15 + 159)/2 = 87

Thus, the number halfway between 15 and 159 is 87.

To check that our answer is correct, we subtract 15 from 87 and subtract 87 from 159 and compare the two numbers:

87 - 15 = 72
159 - 87 = 72

As you can see, the halfway number is 72 higher than 15 and 72 lower than 159. Therefore, our halfway between answer of 87 above is correct.
