Question

Transcribed Image Text:**Q9. Consider the following algorithm:**
```
sum = 0
For j starting at 1 and ending with 15:
sum = sum + (8 * j + 2)
print(sum)
```
**What is printed as a result of executing this algorithm?**
---
This algorithm initializes a variable `sum` to 0. Then, it iterates over the numbers from 1 to 15. For each iteration, it adds the value of `(8 * j + 2)` to `sum`. Finally, it prints the accumulated value of `sum`.
To determine what is printed, calculate:
- For `j = 1`: `sum = 0 + (8*1 + 2) = 10`
- For `j = 2`: `sum = 10 + (8*2 + 2) = 28`
- …
- Continue this pattern up to `j = 15`.
The final printed result is the total of these calculations for each value of `j` from 1 to 15.
