Halfway Between 4 and 220

When you ask "What number is halfway between 4 and 220?" 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=220.

Halfway Between Line

To find the number halfway between 4 and 220, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 220 into our formula, we get:

(4 + 220)/2 = 112

Thus, the number halfway between 4 and 220 is 112.

To check that our answer is correct, we subtract 4 from 112 and subtract 112 from 220 and compare the two numbers:

112 - 4 = 108
220 - 112 = 108

As you can see, the halfway number is 108 higher than 4 and 108 lower than 220. Therefore, our halfway between answer of 112 above is correct.
