Halfway Between 100 and 406

When you ask "What number is halfway between 100 and 406?" 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=406.

Halfway Between Line

To find the number halfway between 100 and 406, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 406 into our formula, we get:

(100 + 406)/2 = 253

Thus, the number halfway between 100 and 406 is 253.

To check that our answer is correct, we subtract 100 from 253 and subtract 253 from 406 and compare the two numbers:

253 - 100 = 153
406 - 253 = 153

As you can see, the halfway number is 153 higher than 100 and 153 lower than 406. Therefore, our halfway between answer of 253 above is correct.
