Halfway Between 84 and 109

When you ask "What number is halfway between 84 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=84 and Y=109.

Halfway Between Line

To find the number halfway between 84 and 109, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 84 and 109 into our formula, we get:

(84 + 109)/2 = 96.5

Thus, the number halfway between 84 and 109 is 96.5.

To check that our answer is correct, we subtract 84 from 96.5 and subtract 96.5 from 109 and compare the two numbers:

96.5 - 84 = 12.5
109 - 96.5 = 12.5

As you can see, the halfway number is 12.5 higher than 84 and 12.5 lower than 109. Therefore, our halfway between answer of 96.5 above is correct.
