Halfway Between 12 and 620

When you ask "What number is halfway between 12 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=12 and Y=620.

Halfway Between Line

To find the number halfway between 12 and 620, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 12 and 620 into our formula, we get:

(12 + 620)/2 = 316

Thus, the number halfway between 12 and 620 is 316.

To check that our answer is correct, we subtract 12 from 316 and subtract 316 from 620 and compare the two numbers:

316 - 12 = 304
620 - 316 = 304

As you can see, the halfway number is 304 higher than 12 and 304 lower than 620. Therefore, our halfway between answer of 316 above is correct.
