Halfway Between 100 and 358

When you ask "What number is halfway between 100 and 358?" 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=358.

Halfway Between Line

To find the number halfway between 100 and 358, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 358 into our formula, we get:

(100 + 358)/2 = 229

Thus, the number halfway between 100 and 358 is 229.

To check that our answer is correct, we subtract 100 from 229 and subtract 229 from 358 and compare the two numbers:

229 - 100 = 129
358 - 229 = 129

As you can see, the halfway number is 129 higher than 100 and 129 lower than 358. Therefore, our halfway between answer of 229 above is correct.
