Halfway Between 30 and 654

When you ask "What number is halfway between 30 and 654?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=30 and Y=654.

Halfway Between Line

To find the number halfway between 30 and 654, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 654 into our formula, we get:

(30 + 654)/2 = 342

Thus, the number halfway between 30 and 654 is 342.

To check that our answer is correct, we subtract 30 from 342 and subtract 342 from 654 and compare the two numbers:

342 - 30 = 312
654 - 342 = 312

As you can see, the halfway number is 312 higher than 30 and 312 lower than 654. Therefore, our halfway between answer of 342 above is correct.
