Halfway Between 53 and 66

When you ask "What number is halfway between 53 and 66?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=53 and Y=66.

Halfway Between Line

To find the number halfway between 53 and 66, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 53 and 66 into our formula, we get:

(53 + 66)/2 = 59.5

Thus, the number halfway between 53 and 66 is 59.5.

To check that our answer is correct, we subtract 53 from 59.5 and subtract 59.5 from 66 and compare the two numbers:

59.5 - 53 = 6.5
66 - 59.5 = 6.5

As you can see, the halfway number is 6.5 higher than 53 and 6.5 lower than 66. Therefore, our halfway between answer of 59.5 above is correct.
