Halfway Between 4 and 402

When you ask "What number is halfway between 4 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=4 and Y=402.

Halfway Between Line

To find the number halfway between 4 and 402, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 4 and 402 into our formula, we get:

(4 + 402)/2 = 203

Thus, the number halfway between 4 and 402 is 203.

To check that our answer is correct, we subtract 4 from 203 and subtract 203 from 402 and compare the two numbers:

203 - 4 = 199
402 - 203 = 199

As you can see, the halfway number is 199 higher than 4 and 199 lower than 402. Therefore, our halfway between answer of 203 above is correct.
