Halfway Between 65 and 138

When you ask "What number is halfway between 65 and 138?" 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=138.

Halfway Between Line

To find the number halfway between 65 and 138, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 65 and 138 into our formula, we get:

(65 + 138)/2 = 101.5

Thus, the number halfway between 65 and 138 is 101.5.

To check that our answer is correct, we subtract 65 from 101.5 and subtract 101.5 from 138 and compare the two numbers:

101.5 - 65 = 36.5
138 - 101.5 = 36.5

As you can see, the halfway number is 36.5 higher than 65 and 36.5 lower than 138. Therefore, our halfway between answer of 101.5 above is correct.
