Halfway Between 30 and 620

When you ask "What number is halfway between 30 and 620?" 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=620.

Halfway Between Line

To find the number halfway between 30 and 620, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 30 and 620 into our formula, we get:

(30 + 620)/2 = 325

Thus, the number halfway between 30 and 620 is 325.

To check that our answer is correct, we subtract 30 from 325 and subtract 325 from 620 and compare the two numbers:

325 - 30 = 295
620 - 325 = 295

As you can see, the halfway number is 295 higher than 30 and 295 lower than 620. Therefore, our halfway between answer of 325 above is correct.
