Water freezes at 0C.
If the temperature starts at 41C on day 1 and drops by 1 degree on that day, then 2 degree on day 2, 3 degrees on day 3, 4 degrees on day 4, and so on...
Repeat this pattern to find how many days it will take for the water to freeze.
<(X)----(Y)--------0----5----------(Z)>
5 is exactly between X and Y.
Y is 14 less than 5.
