Halfway Between 80 and 620

When you ask "What number is halfway between 80 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=80 and Y=620.

Halfway Between Line

To find the number halfway between 80 and 620, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 80 and 620 into our formula, we get:

(80 + 620)/2 = 350

Thus, the number halfway between 80 and 620 is 350.

To check that our answer is correct, we subtract 80 from 350 and subtract 350 from 620 and compare the two numbers:

350 - 80 = 270
620 - 350 = 270

As you can see, the halfway number is 270 higher than 80 and 270 lower than 620. Therefore, our halfway between answer of 350 above is correct.
