Halfway Between 51 and 55

When you ask "What number is halfway between 51 and 55?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=51 and Y=55.

Halfway Between Line

To find the number halfway between 51 and 55, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 51 and 55 into our formula, we get:

(51 + 55)/2 = 53

Thus, the number halfway between 51 and 55 is 53.

To check that our answer is correct, we subtract 51 from 53 and subtract 53 from 55 and compare the two numbers:

53 - 51 = 2
55 - 53 = 2

As you can see, the halfway number is 2 higher than 51 and 2 lower than 55. Therefore, our halfway between answer of 53 above is correct.
