Halfway Between 20 and 438

When you ask "What number is halfway between 20 and 438?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=20 and Y=438.

Halfway Between Line

To find the number halfway between 20 and 438, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 438 into our formula, we get:

(20 + 438)/2 = 229

Thus, the number halfway between 20 and 438 is 229.

To check that our answer is correct, we subtract 20 from 229 and subtract 229 from 438 and compare the two numbers:

229 - 20 = 209
438 - 229 = 209

As you can see, the halfway number is 209 higher than 20 and 209 lower than 438. Therefore, our halfway between answer of 229 above is correct.
