Halfway Between 57 and 117

When you ask "What number is halfway between 57 and 117?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=57 and Y=117.

Halfway Between Line

To find the number halfway between 57 and 117, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 57 and 117 into our formula, we get:

(57 + 117)/2 = 87

Thus, the number halfway between 57 and 117 is 87.

To check that our answer is correct, we subtract 57 from 87 and subtract 87 from 117 and compare the two numbers:

87 - 57 = 30
117 - 87 = 30

As you can see, the halfway number is 30 higher than 57 and 30 lower than 117. Therefore, our halfway between answer of 87 above is correct.
