Halfway Between 89 and 151

When you ask "What number is halfway between 89 and 151?" 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=151.

Halfway Between Line

To find the number halfway between 89 and 151, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 89 and 151 into our formula, we get:

(89 + 151)/2 = 120

Thus, the number halfway between 89 and 151 is 120.

To check that our answer is correct, we subtract 89 from 120 and subtract 120 from 151 and compare the two numbers:

120 - 89 = 31
151 - 120 = 31

As you can see, the halfway number is 31 higher than 89 and 31 lower than 151. Therefore, our halfway between answer of 120 above is correct.
