2. REAL LIFE PROBLEM
• A man was very overweight and his
doctor told him to lose 36 kg. If he
loses 11 kg the first week, 9 kg the
second week, and 7 kg the third
week, and he continues losing at this
rate, how long will it take him to lose
36 kg? (Hint: Look for a pattern.
Then complete the table.)

3. WEEK TOTAL KG LOST
1 11
2 11+9 = 20
3 20+7 = 27
4
5

4. UNDERSTANDING THE PROBLEM
• How much does the man need to lose?
(36 kg)
· How much did he lose the first week?
(11 kg)
· How much did he lose the second
week? (9 kg)
· How much did he lose the third week?
(7 kg)

5. PLANNING A SOLUTION
• How much less does he lose the
second week than the first week? (2
kg)
• How much less does he lose the
third week than the secornd? (2 kg)

6. FINDING THE ANSWER
• Make a Table/ Look for a Pattern
WEEK TOTAL KG LOST
1 11
2 11 + 9 = 20
3 20 + 7 = 27
4 27 + 5 = 32
5 32 + 3 = 35
6 35 + 1 = 36

7. • Pattern: The number of kilograms
lost decreases by 2 each week.
• It will take the man 6 weeks to lose
36 kg.
