Halfway Between 100 and 254

When you ask "What number is halfway between 100 and 254?" 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=254.

Halfway Between Line

To find the number halfway between 100 and 254, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 254 into our formula, we get:

(100 + 254)/2 = 177

Thus, the number halfway between 100 and 254 is 177.

To check that our answer is correct, we subtract 100 from 177 and subtract 177 from 254 and compare the two numbers:

177 - 100 = 77
254 - 177 = 77

As you can see, the halfway number is 77 higher than 100 and 77 lower than 254. Therefore, our halfway between answer of 177 above is correct.
