Question #1300213

How do you get the pattern?

In a school there is a row of 25 lockers numbered from 1-25. A student goes down the row and opens every lock, a second student goes down the row and closes every other locker beginning with locker 2. A third student changes every 3rd locker beginning with locker three, ( if the locker is closed it is opened) a fourth student changes every locker starting with locker 4 this continues until 24 students have gone down the row What would the pattern be at the end?
