6) Given: T(1) = 3 T(N) = T(N-1) + 3, N>1 What would the value of T(10) be?

7) For the problem above, is there a formula that could directly calculate T(N)? 8) Using induction, prove that your formula for the previous problem is correct. 9) Write a generic class (using Java generics) called Pair that stores two values of the generic type. It should have a constructor to set them, two methods getfirst() and getsecond() to retrieve them, and a method called swap() that exchanges them. Include a "main" method that creates a Pair of strings and swaps them, printing the before and after values. You should provide a source file(s) as your solution to this problem.
