Halfway Between 1 and 89

When you ask "What number is halfway between 1 and 89?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=1 and Y=89.

Halfway Between Line

To find the number halfway between 1 and 89, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 1 and 89 into our formula, we get:

(1 + 89)/2 = 45

Thus, the number halfway between 1 and 89 is 45.

To check that our answer is correct, we subtract 1 from 45 and subtract 45 from 89 and compare the two numbers:

45 - 1 = 44
89 - 45 = 44

As you can see, the halfway number is 44 higher than 1 and 44 lower than 89. Therefore, our halfway between answer of 45 above is correct.
