Question:
Predict the number of squares in the next three stages, and write the sequence up to Stage 7. [Page No. 22]
Answer:
Verified
Each stage adds 2 tiles to the one before, so the counts go up by 2 each time:
| Stage | Number of tiles |
|---|---|
| 1 | 1 |
| 2 | 3 |
| 3 | 5 |
| 4 | 7 |
| 5 | 9 |
| 6 | 11 |
| 7 | 13 |
Stage 4 has 7 tiles, so the next three stages are Stage 5 = 9, Stage 6 = 11, Stage 7 = 13.
The full sequence is 1, 3, 5, 7, 9, 11, 13 (the odd numbers).
