Halfway Between 3 and 109

When you ask "What number is halfway between 3 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=3 and Y=109.

Halfway Between Line

To find the number halfway between 3 and 109, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 3 and 109 into our formula, we get:

(3 + 109)/2 = 56

Thus, the number halfway between 3 and 109 is 56.

To check that our answer is correct, we subtract 3 from 56 and subtract 56 from 109 and compare the two numbers:

56 - 3 = 53
109 - 56 = 53

As you can see, the halfway number is 53 higher than 3 and 53 lower than 109. Therefore, our halfway between answer of 56 above is correct.
