Halfway Between 31 and 402

When you ask "What number is halfway between 31 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=31 and Y=402.

Halfway Between Line

To find the number halfway between 31 and 402, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 31 and 402 into our formula, we get:

(31 + 402)/2 = 216.5

Thus, the number halfway between 31 and 402 is 216.5.

To check that our answer is correct, we subtract 31 from 216.5 and subtract 216.5 from 402 and compare the two numbers:

216.5 - 31 = 185.5
402 - 216.5 = 185.5

As you can see, the halfway number is 185.5 higher than 31 and 185.5 lower than 402. Therefore, our halfway between answer of 216.5 above is correct.
