Halfway Between 45 and 620

When you ask "What number is halfway between 45 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=45 and Y=620.

Halfway Between Line

To find the number halfway between 45 and 620, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 45 and 620 into our formula, we get:

(45 + 620)/2 = 332.5

Thus, the number halfway between 45 and 620 is 332.5.

To check that our answer is correct, we subtract 45 from 332.5 and subtract 332.5 from 620 and compare the two numbers:

332.5 - 45 = 287.5
620 - 332.5 = 287.5

As you can see, the halfway number is 287.5 higher than 45 and 287.5 lower than 620. Therefore, our halfway between answer of 332.5 above is correct.
