Halfway Between 85 and 158

When you ask "What number is halfway between 85 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=85 and Y=158.

Halfway Between Line

To find the number halfway between 85 and 158, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 158 into our formula, we get:

(85 + 158)/2 = 121.5

Thus, the number halfway between 85 and 158 is 121.5.

To check that our answer is correct, we subtract 85 from 121.5 and subtract 121.5 from 158 and compare the two numbers:

121.5 - 85 = 36.5
158 - 121.5 = 36.5

As you can see, the halfway number is 36.5 higher than 85 and 36.5 lower than 158. Therefore, our halfway between answer of 121.5 above is correct.
