Halfway Between 66 and 615

When you ask "What number is halfway between 66 and 615?" 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=615.

Halfway Between Line

To find the number halfway between 66 and 615, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 66 and 615 into our formula, we get:

(66 + 615)/2 = 340.5

Thus, the number halfway between 66 and 615 is 340.5.

To check that our answer is correct, we subtract 66 from 340.5 and subtract 340.5 from 615 and compare the two numbers:

340.5 - 66 = 274.5
615 - 340.5 = 274.5

As you can see, the halfway number is 274.5 higher than 66 and 274.5 lower than 615. Therefore, our halfway between answer of 340.5 above is correct.
