I'll work through each problem step by step to find the correct answers.
Problem 1: 35, 45, 55, __, __, __
- Looking at the pattern: 35 → 45 (add 10), 45 → 55 (add 10)
- The pattern is adding 10 each time
- Next numbers: 55 + 10 = 65, 65 + 10 = 75, 75 + 10 = 85
- Answer: 65, 75, 85
- This matches option A
Problem 2: 92, 102, 112, 122, 132, 142
- Looking at the differences: 102 - 92 = 10, 112 - 102 = 10, etc.
- Each number increases by 10
- The pattern rule is: add 10
- This matches option C
Problem 3: Start with 65. Count by 5s. What are the next 4 numbers?
- Starting at 65, add 5 each time
- 65 + 5 = 70
- 70 + 5 = 75
- 75 + 5 = 80
- 80 + 5 = 85
- Answer: 70, 75, 80, 85
Problem 4: Start with 824. Count by 10s. What are the next 4 numbers?
- Starting at 824, add 10 each time
- 824 + 10 = 834
- 834 + 10 = 844
- 844 + 10 = 854
- 854 + 10 = 864
- Answer: 834, 844, 854, 864
Problem 5: Cupcake sales pattern
- Monday: 14 cupcakes
- Tuesday: 24 cupcakes (difference: 24 - 14 = 10)
- Wednesday: 34 cupcakes (difference: 34 - 24 = 10)
- The pattern is adding 10 each day
- Thursday: 34 + 10 = 44 cupcakes
- Friday: 44 + 10 = 54 cupcakes
Let me verify my calculations one more time:
1. ✓ 35, 45, 55, 65, 75, 85 (adding 10)
2. ✓ Pattern rule is add 10
3. ✓ 65, 70, 75, 80, 85 (counting by 5s)
4. ✓ 824, 834, 844, 854, 864 (counting by 10s)
5. ✓ Thursday: 44, Friday: 54 (adding 10 each day)
Final Answer:
1. A (65, 75, 85)
2. C (10)
3. 70, 75, 80, 85
4. 834, 844, 854, 864
5. Thursday: 44 cupcakes, Friday: 54 cupcakes
