Halfway Between 4 and 427

When you ask "What number is halfway between 4 and 427?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=4 and Y=427.

Halfway Between Line

To find the number halfway between 4 and 427, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 427 into our formula, we get:

(4 + 427)/2 = 215.5

Thus, the number halfway between 4 and 427 is 215.5.

To check that our answer is correct, we subtract 4 from 215.5 and subtract 215.5 from 427 and compare the two numbers:

215.5 - 4 = 211.5
427 - 215.5 = 211.5

As you can see, the halfway number is 211.5 higher than 4 and 211.5 lower than 427. Therefore, our halfway between answer of 215.5 above is correct.
