Halfway Between 86 and 138

When you ask "What number is halfway between 86 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=86 and Y=138.

Halfway Between Line

To find the number halfway between 86 and 138, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 86 and 138 into our formula, we get:

(86 + 138)/2 = 112

Thus, the number halfway between 86 and 138 is 112.

To check that our answer is correct, we subtract 86 from 112 and subtract 112 from 138 and compare the two numbers:

112 - 86 = 26
138 - 112 = 26

As you can see, the halfway number is 26 higher than 86 and 26 lower than 138. Therefore, our halfway between answer of 112 above is correct.
