Halfway Between 100 and 719

When you ask "What number is halfway between 100 and 719?" 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=719.

Halfway Between Line

To find the number halfway between 100 and 719, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 719 into our formula, we get:

(100 + 719)/2 = 409.5

Thus, the number halfway between 100 and 719 is 409.5.

To check that our answer is correct, we subtract 100 from 409.5 and subtract 409.5 from 719 and compare the two numbers:

409.5 - 100 = 309.5
719 - 409.5 = 309.5

As you can see, the halfway number is 309.5 higher than 100 and 309.5 lower than 719. Therefore, our halfway between answer of 409.5 above is correct.
