Halfway Between 100 and 380

When you ask "What number is halfway between 100 and 380?" 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=380.

Halfway Between Line

To find the number halfway between 100 and 380, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 380 into our formula, we get:

(100 + 380)/2 = 240

Thus, the number halfway between 100 and 380 is 240.

To check that our answer is correct, we subtract 100 from 240 and subtract 240 from 380 and compare the two numbers:

240 - 100 = 140
380 - 240 = 140

As you can see, the halfway number is 140 higher than 100 and 140 lower than 380. Therefore, our halfway between answer of 240 above is correct.
