Halfway Between 2 and 109

When you ask "What number is halfway between 2 and 109?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=2 and Y=109.

Halfway Between Line

To find the number halfway between 2 and 109, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 2 and 109 into our formula, we get:

(2 + 109)/2 = 55.5

Thus, the number halfway between 2 and 109 is 55.5.

To check that our answer is correct, we subtract 2 from 55.5 and subtract 55.5 from 109 and compare the two numbers:

55.5 - 2 = 53.5
109 - 55.5 = 53.5

As you can see, the halfway number is 53.5 higher than 2 and 53.5 lower than 109. Therefore, our halfway between answer of 55.5 above is correct.
