Halfway Between 99 and 629

When you ask "What number is halfway between 99 and 629?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=99 and Y=629.

Halfway Between Line

To find the number halfway between 99 and 629, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 99 and 629 into our formula, we get:

(99 + 629)/2 = 364

Thus, the number halfway between 99 and 629 is 364.

To check that our answer is correct, we subtract 99 from 364 and subtract 364 from 629 and compare the two numbers:

364 - 99 = 265
629 - 364 = 265

As you can see, the halfway number is 265 higher than 99 and 265 lower than 629. Therefore, our halfway between answer of 364 above is correct.
