Halfway Between 15 and 118

When you ask "What number is halfway between 15 and 118?" 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=118.

Halfway Between Line

To find the number halfway between 15 and 118, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 15 and 118 into our formula, we get:

(15 + 118)/2 = 66.5

Thus, the number halfway between 15 and 118 is 66.5.

To check that our answer is correct, we subtract 15 from 66.5 and subtract 66.5 from 118 and compare the two numbers:

66.5 - 15 = 51.5
118 - 66.5 = 51.5

As you can see, the halfway number is 51.5 higher than 15 and 51.5 lower than 118. Therefore, our halfway between answer of 66.5 above is correct.
