• Application:
• Comparison of historical returns on assets (stocks, bonds).
• Evaluation of growth in business indicators (sales, market share).
• Forecasting future values based on past data.
• Advantages:
• Simplifies comparison of growth over different periods.

• Limitations:
• Does not reflect volatility (for example, sharp declines or growth spurts in individual years).
• Can be misleading when analyzing short-term trends.
• Does not take into account external factors (inflation, market changes).
