Halfway Between 100 and 979

When you ask "What number is halfway between 100 and 979?" 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=979.

Halfway Between Line

To find the number halfway between 100 and 979, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 100 and 979 into our formula, we get:

(100 + 979)/2 = 539.5

Thus, the number halfway between 100 and 979 is 539.5.

To check that our answer is correct, we subtract 100 from 539.5 and subtract 539.5 from 979 and compare the two numbers:

539.5 - 100 = 439.5
979 - 539.5 = 439.5

As you can see, the halfway number is 439.5 higher than 100 and 439.5 lower than 979. Therefore, our halfway between answer of 539.5 above is correct.
