To solve the problem, we need to identify the pattern in each sequence and use skip-counting to fill in the missing numbers. Let's go through each sequence step by step.
---
Sequence 1:
20, 30, 40, ______, 60, 70
- The sequence increases by
10 each time.
- The missing number is \( 40 + 10 = 50 \).
Answer: 50
---
Sequence 2:
______, 250, 200, 150, 100, 50
- The sequence decreases by
50 each time.
- The missing number is \( 250 + 50 = 300 \).
Answer: 300
---
Sequence 3:
45, 40, 35, ______, 25, 20
- The sequence decreases by
5 each time.
- The missing number is \( 35 - 5 = 30 \).
Answer: 30
---
Sequence 4:
282, 280, ______, 276, 274, 272
- The sequence decreases by
2 each time.
- The missing number is \( 280 - 2 = 278 \).
Answer: 278
---
Sequence 5:
30, ______, 36, 39, 42, 45
- The sequence increases by
3 each time.
- The missing number is \( 30 + 3 = 33 \).
Answer: 33
---
Sequence 6:
400, 375, 350, ______, 300, 275
- The sequence decreases by
25 each time.
- The missing number is \( 350 - 25 = 325 \).
Answer: 325
---
Final Answers:
1. 50
2. 300
3. 30
4. 278
5. 33
6. 325
Boxed Answer:
\[
\boxed{50, 300, 30, 278, 33, 325}
\]
