You can put this solution on YOUR website! The first two terms of a sequence are a, b. From then on, each term is equal to the opposite of the previous term, plus the term before that. What is the sixth term?
a
b
-b + a --> a - b
-(a - b) + b --> -a + b + b --> 2b - a
-(2b - a) + a - b --> -2b + a + a - b --> 2a - 3b
-(2a - 3b) + 2b - a --> -2a + 3b + 2b - a --> 5b - 3a (6th term)
