Halfway Between 80 and 158

When you ask "What number is halfway between 80 and 158?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=80 and Y=158.

Halfway Between Line

To find the number halfway between 80 and 158, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 158 into our formula, we get:

(80 + 158)/2 = 119

Thus, the number halfway between 80 and 158 is 119.

To check that our answer is correct, we subtract 80 from 119 and subtract 119 from 158 and compare the two numbers:

119 - 80 = 39
158 - 119 = 39

As you can see, the halfway number is 39 higher than 80 and 39 lower than 158. Therefore, our halfway between answer of 119 above is correct.
