Question
Write a RECURSIVE method called “sequence” that takes a single int parameter (n) and returns the int value of the nth element of the sequence S = 2, 4, 6, 12, 22, 40, 74, 136, 250, 460, …
Where S is defined by the recursive formula:
For n >= 0
S(0) = 2; // Base case 1
S(1) = 4; // Base case 2
S(2) = 6; // Base case 3
S(N) = 2 * ( S(N-1)/2 + S(N-2)/2 + S(N-3)/2)
