Halfway Between 13 and 620

When you ask "What number is halfway between 13 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=13 and Y=620.

Halfway Between Line

To find the number halfway between 13 and 620, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 13 and 620 into our formula, we get:

(13 + 620)/2 = 316.5

Thus, the number halfway between 13 and 620 is 316.5.

To check that our answer is correct, we subtract 13 from 316.5 and subtract 316.5 from 620 and compare the two numbers:

316.5 - 13 = 303.5
620 - 316.5 = 303.5

As you can see, the halfway number is 303.5 higher than 13 and 303.5 lower than 620. Therefore, our halfway between answer of 316.5 above is correct.
