Halfway Between 20 and 450

When you ask "What number is halfway between 20 and 450?" 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=450.

Halfway Between Line

To find the number halfway between 20 and 450, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 450 into our formula, we get:

(20 + 450)/2 = 235

Thus, the number halfway between 20 and 450 is 235.

To check that our answer is correct, we subtract 20 from 235 and subtract 235 from 450 and compare the two numbers:

235 - 20 = 215
450 - 235 = 215

As you can see, the halfway number is 215 higher than 20 and 215 lower than 450. Therefore, our halfway between answer of 235 above is correct.
