Halfway Between 85 and 145

When you ask "What number is halfway between 85 and 145?" 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=145.

Halfway Between Line

To find the number halfway between 85 and 145, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 85 and 145 into our formula, we get:

(85 + 145)/2 = 115

Thus, the number halfway between 85 and 145 is 115.

To check that our answer is correct, we subtract 85 from 115 and subtract 115 from 145 and compare the two numbers:

115 - 85 = 30
145 - 115 = 30

As you can see, the halfway number is 30 higher than 85 and 30 lower than 145. Therefore, our halfway between answer of 115 above is correct.
