This is a simple exercise for finding recursive equations and writing them as Java code.

1. Whiteboard

2. Access to a Java editor

1) Give each row a sequence of numbers.

Ex:

a) 2, 6, 10, 14,...

b) 0, 1, 0, 1...

c) 2, 6, 12, 20...

d) 1, 4, 9, 16...

2) Then have each row work together to find the recursive definition for the sequences.

Ex:

a) 4n-2

b) 1+(-1)^n

c) n(n + 1)

d) n^2

3) Lastly, each group should write Java code to implement the recursive equation and submit via Google Docs.

Ex:

a)

public int recursion( int n ){

   int a = 0;
   if(n == 1) a = 2;
   else a = recursion( n - 1 ) + 4;
   return a;

}
