Halfway Between 100 and 629

When you ask "What number is halfway between 100 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=100 and Y=629.

Halfway Between Line

To find the number halfway between 100 and 629, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 629 into our formula, we get:

(100 + 629)/2 = 364.5

Thus, the number halfway between 100 and 629 is 364.5.

To check that our answer is correct, we subtract 100 from 364.5 and subtract 364.5 from 629 and compare the two numbers:

364.5 - 100 = 264.5
629 - 364.5 = 264.5

As you can see, the halfway number is 264.5 higher than 100 and 264.5 lower than 629. Therefore, our halfway between answer of 364.5 above is correct.
