Halfway Between 66 and 291

When you ask "What number is halfway between 66 and 291?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=66 and Y=291.

Halfway Between Line

To find the number halfway between 66 and 291, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 291 into our formula, we get:

(66 + 291)/2 = 178.5

Thus, the number halfway between 66 and 291 is 178.5.

To check that our answer is correct, we subtract 66 from 178.5 and subtract 178.5 from 291 and compare the two numbers:

178.5 - 66 = 112.5
291 - 178.5 = 112.5

As you can see, the halfway number is 112.5 higher than 66 and 112.5 lower than 291. Therefore, our halfway between answer of 178.5 above is correct.
