1. The problem appears to involve evaluating or simplifying the expression given in the first column labeled "5)" with terms 3, 3, 1, -1 ending at 2. 2. We interpret this as a sequence or sum: $3 + 3 + 1 - 1 = ?$ 3. Add the first two terms: $3 + 3 = 6$ 4. Add the next term: $6 + 1 = 7$ 5. Subtract the last term: $7 - 1 = 6$ 6. Therefore, the final result is $6$.
