Halfway Between 100 and 350

When you ask "What number is halfway between 100 and 350?" 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=350.

Halfway Between Line

To find the number halfway between 100 and 350, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 350 into our formula, we get:

(100 + 350)/2 = 225

Thus, the number halfway between 100 and 350 is 225.

To check that our answer is correct, we subtract 100 from 225 and subtract 225 from 350 and compare the two numbers:

225 - 100 = 125
350 - 225 = 125

As you can see, the halfway number is 125 higher than 100 and 125 lower than 350. Therefore, our halfway between answer of 225 above is correct.
