Halfway Between 3 and 615

When you ask "What number is halfway between 3 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=3 and Y=615.

Halfway Between Line

To find the number halfway between 3 and 615, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 3 and 615 into our formula, we get:

(3 + 615)/2 = 309

Thus, the number halfway between 3 and 615 is 309.

To check that our answer is correct, we subtract 3 from 309 and subtract 309 from 615 and compare the two numbers:

309 - 3 = 306
615 - 309 = 306

As you can see, the halfway number is 306 higher than 3 and 306 lower than 615. Therefore, our halfway between answer of 309 above is correct.
