5. Fill in the missing number in the pattern.

12,500 | 13,000 | 13,500 | ________ | 14,500

• Common difference: 13,000 − 12,500 = 500
• 13,500 + 500 = 14,000
• Check: 14,000 + 500 = 14,500 ✓
• Answer: 14,000 [2 marks]

Section B: Rounding Numbers

6. Round 29,458 to the nearest hundred.

• The hundreds digit is 4; the tens digit is 5.
• Since the tens digit is 5 or more, round up.
• 29,458 → 29,500
• Answer: 29,500 [2 marks]

---

7. Round 73,650 to the nearest thousand.

• The thousands digit is 3; the hundreds digit is 6.
• Since the hundreds digit is 5 or more, round up.

• Answer: 74,000 [2 marks]

---

8. A number rounded to the nearest ten is 45,670. What is the smallest possible value?

• When rounding to the nearest ten, the smallest number that rounds to 45,670 is found by keeping the tens digit and setting the ones digit to 5 (the threshold for rounding up).
• The range is 45,665 to 45,674.
• Answer: 45,665 [2 marks]
• Marking note: Accept 45,665 only. Common mistake: writing 45,671 or 45,660.

---

9. A number rounded to the nearest thousand is 82,000. What is the largest possible value?

• When rounding to the nearest thousand, the largest number that rounds to 82,000 is 82,499 (since 82,500 would round to 83,000).
• Answer: 82,499 [2 marks]
• Marking note: Common mistake: writing 82,999 or 82,500.

---

10. Use the approximation symbol (≈).

61,429 rounded to the nearest hundred.

• The hundreds digit is 4; the tens digit is 2.
• Since the tens digit is less than 5, round down.
• 61,429 → 61,400
• Answer: 61,429 ≈ 61,400 [2 marks]
• Marking note: The ≈ symbol must be used. Award 1 mark if the rounded value is correct but the symbol is missing.
