Halfway Between 100 and 731

When you ask "What number is halfway between 100 and 731?" 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=731.

Halfway Between Line

To find the number halfway between 100 and 731, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 731 into our formula, we get:

(100 + 731)/2 = 415.5

Thus, the number halfway between 100 and 731 is 415.5.

To check that our answer is correct, we subtract 100 from 415.5 and subtract 415.5 from 731 and compare the two numbers:

415.5 - 100 = 315.5
731 - 415.5 = 315.5

As you can see, the halfway number is 315.5 higher than 100 and 315.5 lower than 731. Therefore, our halfway between answer of 415.5 above is correct.
