Halfway Between 30 and 402

When you ask "What number is halfway between 30 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=30 and Y=402.

Halfway Between Line

To find the number halfway between 30 and 402, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 402 into our formula, we get:

(30 + 402)/2 = 216

Thus, the number halfway between 30 and 402 is 216.

To check that our answer is correct, we subtract 30 from 216 and subtract 216 from 402 and compare the two numbers:

216 - 30 = 186
402 - 216 = 186

As you can see, the halfway number is 186 higher than 30 and 186 lower than 402. Therefore, our halfway between answer of 216 above is correct.
