Halfway Between 100 and 428

When you ask "What number is halfway between 100 and 428?" 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=428.

Halfway Between Line

To find the number halfway between 100 and 428, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 428 into our formula, we get:

(100 + 428)/2 = 264

Thus, the number halfway between 100 and 428 is 264.

To check that our answer is correct, we subtract 100 from 264 and subtract 264 from 428 and compare the two numbers:

264 - 100 = 164
428 - 264 = 164

As you can see, the halfway number is 164 higher than 100 and 164 lower than 428. Therefore, our halfway between answer of 264 above is correct.
