Halfway Between 100 and 166

When you ask "What number is halfway between 100 and 166?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=100 and Y=166.

Halfway Between Line

To find the number halfway between 100 and 166, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 166 into our formula, we get:

(100 + 166)/2 = 133

Thus, the number halfway between 100 and 166 is 133.

To check that our answer is correct, we subtract 100 from 133 and subtract 133 from 166 and compare the two numbers:

133 - 100 = 33
166 - 133 = 33

As you can see, the halfway number is 33 higher than 100 and 33 lower than 166. Therefore, our halfway between answer of 133 above is correct.
