N nvv Jan 2009 14 4 Jan 11, 2009 #2 Hi, cj's mom. If I understand You correctly: a. xi = i * 2 | i = 0, inf b. xi = x(i-1) + 3 | i = -inf, inf (i-1) - index c. x0 = 1 xi = 2*x(i-1) + 1 (i-1) - index d. I think here is not enough members to define set. Have You some another members? Reactions: cj's mom
