Halfway Between 65 and 90

When you ask "What number is halfway between 65 and 90?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=65 and Y=90.

Halfway Between Line

To find the number halfway between 65 and 90, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 65 and 90 into our formula, we get:

(65 + 90)/2 = 77.5

Thus, the number halfway between 65 and 90 is 77.5.

To check that our answer is correct, we subtract 65 from 77.5 and subtract 77.5 from 90 and compare the two numbers:

77.5 - 65 = 12.5
90 - 77.5 = 12.5

As you can see, the halfway number is 12.5 higher than 65 and 12.5 lower than 90. Therefore, our halfway between answer of 77.5 above is correct.
