Halfway Between 65 and 109

When you ask "What number is halfway between 65 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=65 and Y=109.

Halfway Between Line

To find the number halfway between 65 and 109, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 65 and 109 into our formula, we get:

(65 + 109)/2 = 87

Thus, the number halfway between 65 and 109 is 87.

To check that our answer is correct, we subtract 65 from 87 and subtract 87 from 109 and compare the two numbers:

87 - 65 = 22
109 - 87 = 22

As you can see, the halfway number is 22 higher than 65 and 22 lower than 109. Therefore, our halfway between answer of 87 above is correct.
