Halfway Between 30 and 310

When you ask "What number is halfway between 30 and 310?" 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=310.

Halfway Between Line

To find the number halfway between 30 and 310, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 310 into our formula, we get:

(30 + 310)/2 = 170

Thus, the number halfway between 30 and 310 is 170.

To check that our answer is correct, we subtract 30 from 170 and subtract 170 from 310 and compare the two numbers:

170 - 30 = 140
310 - 170 = 140

As you can see, the halfway number is 140 higher than 30 and 140 lower than 310. Therefore, our halfway between answer of 170 above is correct.
