S(0) = 1, S(1) = 0, and S(n+1) = 3S(n) – 2S(n-1)

Express S(n) as a function of n.

And the letters/numbers in parenthesis are supposed to be subscripts of each S.

These are the first 6 numbers in the sequence.

S(0) = 1

S(1) = 0

S(2) = -2

S(3) = -6

S(4) = -14

S(5) = -30

S(6) = -62

Any help?
