Halfway Between 20 and 402

When you ask "What number is halfway between 20 and 402?" 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=402.

Halfway Between Line

To find the number halfway between 20 and 402, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 20 and 402 into our formula, we get:

(20 + 402)/2 = 211

Thus, the number halfway between 20 and 402 is 211.

To check that our answer is correct, we subtract 20 from 211 and subtract 211 from 402 and compare the two numbers:

211 - 20 = 191
402 - 211 = 191

As you can see, the halfway number is 191 higher than 20 and 191 lower than 402. Therefore, our halfway between answer of 211 above is correct.
