Halfway Between 66 and 629

When you ask "What number is halfway between 66 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=66 and Y=629.

Halfway Between Line

To find the number halfway between 66 and 629, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 629 into our formula, we get:

(66 + 629)/2 = 347.5

Thus, the number halfway between 66 and 629 is 347.5.

To check that our answer is correct, we subtract 66 from 347.5 and subtract 347.5 from 629 and compare the two numbers:

347.5 - 66 = 281.5
629 - 347.5 = 281.5

As you can see, the halfway number is 281.5 higher than 66 and 281.5 lower than 629. Therefore, our halfway between answer of 347.5 above is correct.
