Class 9 Chapter 8: Predicting What Comes Next: Exploring Sequences and Progressions Test Series -1 Results #1. Which is a sequence? 5, 2, 9 1, 2, 3, 4 Random values None #2. Which sequence is infinite? 1, 2, 3, … 2, 4, 6 5, 10 None #3. Difference between consecutive odd numbers is: 1 2 3 4 #4. Sequence 1, 1/2, 1/3, 1/4,… is: Increasing Decreasing Constant Random #5. If uₙ = 2n – 1, then u₃ = 3 5 7 9 #6. For sₙ = 5n – 2, s₂ = 8 10 12 6 #7. In tₙ = tₙ₋₁ + 3, sequence is: Increasing by 3 Decreasing by 3 Random Constant #8. First four terms of u₁=1, uₙ=2uₙ₋₁+3: 1, 5, 13, 29 1, 3, 5, 7 2, 4, 6, 8 1, 4, 7, 10 #9. AP has: Constant ratio Constant difference Random difference No pattern #10. For AP 1, 4, 7, 10,… t₅ = 10 13 15 16 Previous Finish
