Halfway Between 36 and 138

When you ask "What number is halfway between 36 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=36 and Y=138.

Halfway Between Line

To find the number halfway between 36 and 138, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 36 and 138 into our formula, we get:

(36 + 138)/2 = 87

Thus, the number halfway between 36 and 138 is 87.

To check that our answer is correct, we subtract 36 from 87 and subtract 87 from 138 and compare the two numbers:

87 - 36 = 51
138 - 87 = 51

As you can see, the halfway number is 51 higher than 36 and 51 lower than 138. Therefore, our halfway between answer of 87 above is correct.
