Question 1
Mr Quantik records test scores in a special way. The maximum score is 15, and each score is represented by a sequence of trees and stones.
The table shows an example of how to calculate the score. We count only the values at positions occupied by trees.
| Position | Position 1 | Position 2 | Position 3 | Position 4 | Score |
|---|---|---|---|---|---|
| Value | 8 points | 4 points | 2 points | 1 point | |
| Symbol | Tree | Stone | Stone | Tree | $8+1=9$ |
What score does the following sequence represent?
