Halfway Between 10 and 628

When you ask "What number is halfway between 10 and 628?" 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=628.

Halfway Between Line

To find the number halfway between 10 and 628, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 10 and 628 into our formula, we get:

(10 + 628)/2 = 319

Thus, the number halfway between 10 and 628 is 319.

To check that our answer is correct, we subtract 10 from 319 and subtract 319 from 628 and compare the two numbers:

319 - 10 = 309
628 - 319 = 309

As you can see, the halfway number is 309 higher than 10 and 309 lower than 628. Therefore, our halfway between answer of 319 above is correct.
