Halfway Between 100 and 378




When you ask "What number is halfway between 100 and 378?" 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=378.



To find the number halfway between 100 and 378, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 378 into our formula, we get:

(100 + 378)/2 = 239

Thus, the number halfway between 100 and 378 is 239.


To check that our answer is correct, we subtract 100 from 239 and subtract 239 from 378 and compare the two numbers:

239 - 100 = 139
378 - 239 = 139

As you can see, the halfway number is 139 higher than 100 and 139 lower than 378. Therefore, our halfway between answer of 239 above is correct.
