To determine the number of possible bullying cases by the end of this year, we need to calculate the constant yearly increase in bullying cases from 2013 to 2018 and then project that increase forward to 2024.

First, we identify the years involved:

1. From 2013 to 2018, there are 6 years (2018 - 2013 = 5 + 1 because both endpoints are included).

Next, we calculate the constant yearly increase:

$\text{Yearly Increase} = \frac{\text{Increase in cases}}{\text{Number of years}} = \frac{20172 - 1158}{6} = \frac{19014}{6} = 3169$

The constant increase in bullying cases per year is 3169 cases.

Now, we will project this increase forward from 2018 to 2024:

1. From 2018 to 2024, there are 6 years (2024 - 2018).

Finally, we calculate the total number of cases by the end of 2024:

$\text{Cases in 2024} = \text{Cases in 2018} + (\text{Yearly Increase} \times \text{Number of years from 2018 to 2024})$

$\text{Cases in 2024} = 20172 + (3169 \times 6) = 20172 + 19014 = 39186$

Therefore, the number of possible bullying cases by the end of 2024 is 39,186.

Would you like further details or have any questions about this calculation? Here are some related questions to consider:

1. What factors might contribute to the increase in reported bullying cases?
2. How effective has the Anti Bullying Law been since its implementation?
3. Are there any other methods to project future bullying cases besides assuming a constant increase?
4. What steps can schools take to reduce bullying incidents?
5. How can awareness programs impact the number of reported bullying cases?
6. What are the consequences of bullying on students' mental health?
7. Are there differences in bullying cases between different regions or schools?
8. How can data collection on bullying be improved for more accurate projections?

Tip: When analyzing trends over multiple years, consider other factors such as changes in reporting practices or interventions that may affect the numbers.
