Halfway Between 89 and 142

When you ask "What number is halfway between 89 and 142?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=89 and Y=142.

Halfway Between Line

To find the number halfway between 89 and 142, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 142 into our formula, we get:

(89 + 142)/2 = 115.5

Thus, the number halfway between 89 and 142 is 115.5.

To check that our answer is correct, we subtract 89 from 115.5 and subtract 115.5 from 142 and compare the two numbers:

115.5 - 89 = 26.5
142 - 115.5 = 26.5

As you can see, the halfway number is 26.5 higher than 89 and 26.5 lower than 142. Therefore, our halfway between answer of 115.5 above is correct.
