Halfway Between 65 and 91

When you ask "What number is halfway between 65 and 91?" 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=91.

Halfway Between Line

To find the number halfway between 65 and 91, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 65 and 91 into our formula, we get:

(65 + 91)/2 = 78

Thus, the number halfway between 65 and 91 is 78.

To check that our answer is correct, we subtract 65 from 78 and subtract 78 from 91 and compare the two numbers:

78 - 65 = 13
91 - 78 = 13

As you can see, the halfway number is 13 higher than 65 and 13 lower than 91. Therefore, our halfway between answer of 78 above is correct.
