Halfway Between 51 and 117

When you ask "What number is halfway between 51 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=51 and Y=117.

Halfway Between Line

To find the number halfway between 51 and 117, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 51 and 117 into our formula, we get:

(51 + 117)/2 = 84

Thus, the number halfway between 51 and 117 is 84.

To check that our answer is correct, we subtract 51 from 84 and subtract 84 from 117 and compare the two numbers:

84 - 51 = 33
117 - 84 = 33

As you can see, the halfway number is 33 higher than 51 and 33 lower than 117. Therefore, our halfway between answer of 84 above is correct.
