Halfway Between 10 and 620

When you ask "What number is halfway between 10 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=10 and Y=620.

Halfway Between Line

To find the number halfway between 10 and 620, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 10 and 620 into our formula, we get:

(10 + 620)/2 = 315

Thus, the number halfway between 10 and 620 is 315.

To check that our answer is correct, we subtract 10 from 315 and subtract 315 from 620 and compare the two numbers:

315 - 10 = 305
620 - 315 = 305

As you can see, the halfway number is 305 higher than 10 and 305 lower than 620. Therefore, our halfway between answer of 315 above is correct.
