Question 1: How tall was the plant in week 2?

Look at the row for “Week 2” — it says 5 cm.

✔ Answer: 5 cm

---

Question 2: How much had the plant grown from week 1 to week 2?

Subtract Week 1 height from Week 2 height:

5 cm – 2 cm = 3 cm

✔ Answer: 3 cm

Question 3: How much had the plant grown from week 2 to week 4?

Week 4 height: 11 cm
Week 2 height: 5 cm
Growth = 11 – 5 = 6 cm

✔ Answer: 6 cm

---

Question 4: How much had the plant grown from week 1 to week 5?

Week 5 height: 14 cm
Week 1 height: 2 cm
Growth = 14 – 2 = 12 cm

✔ Answer: 12 cm

Question 5: On week 6, do you think the plant would be around 21 cm or 17 cm?

Let’s look at the pattern of growth:

- Week 1 → Week 2: +3 cm (2 → 5)
- Week 2 → Week 3: +3 cm (5 → 8)
- Week 3 → Week 4: +3 cm (8 → 11)
- Week 4 → Week 5: +3 cm (11 → 14)

So every week, the plant grows exactly 3 cm.

If this continues, then:

Week 5 → Week 6: 14 + 3 = 17 cm

That means on Week 6, the plant should be about 17 cm, not 21 cm.

✔ Answer: 17 cm

Final Answer:
1. 5 cm
2. 3 cm
3. 6 cm
4. 12 cm
