Halfway Between 55 and 91

When you ask "What number is halfway between 55 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=55 and Y=91.

Halfway Between Line

To find the number halfway between 55 and 91, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 55 and 91 into our formula, we get:

(55 + 91)/2 = 73

Thus, the number halfway between 55 and 91 is 73.

To check that our answer is correct, we subtract 55 from 73 and subtract 73 from 91 and compare the two numbers:

73 - 55 = 18
91 - 73 = 18

As you can see, the halfway number is 18 higher than 55 and 18 lower than 91. Therefore, our halfway between answer of 73 above is correct.
