Halfway Between 85 and 155

When you ask "What number is halfway between 85 and 155?" 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=155.

Halfway Between Line

To find the number halfway between 85 and 155, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 155 into our formula, we get:

(85 + 155)/2 = 120

Thus, the number halfway between 85 and 155 is 120.

To check that our answer is correct, we subtract 85 from 120 and subtract 120 from 155 and compare the two numbers:

120 - 85 = 35
155 - 120 = 35

As you can see, the halfway number is 35 higher than 85 and 35 lower than 155. Therefore, our halfway between answer of 120 above is correct.
