🤖 Ai回答: 要确定香港2月的平均气温,我们需要 know the average temperature for each day in February and then find the average of those daily temperatures、However, since the specific daily temperatures are not provided in the problem, I will use a hypothetical example to illustrate the process.
Let's assume the daily temperatures for February (which has 28 days) are as follows (in degrees Celsius):
Day 1: 10°C
Day 2: 12°C
Day 3: 14°C
Day 4: 16°C
Day 5: 18°C
Day 6: 20°C
Day 7: 22°C
Day 8: 24°C
Day 9: 26°C
Day 10: 28°C
Day 11: 30°C
Day 12: 32°C
Day 13: 34°C
Day 14: 36°C
Day 15: 38°C
Day 16: 40°C
Day 17: 42°C
Day 18: 44°C
Day 19: 46°C
Day 20: 48°C
Day 21: 50°C
Day 22: 52°C
Day 23: 54°C
Day 24: 56°C
Day 25: 58°C
Day 26: 60°C
Day 27: 62°C
Day 28: 64°C
This is an arithmetic series where the first term \(a = 10\), the last term \(l = 64\), and the number of terms \(n = 28\)、The sum \(S_n\) of an arithmetic series is given by:
