🗣 Wd提问: 香港2月平均气温

🤖 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

First, we sum all the daily temperatures:

\[10 + 12 + 14 + 16 + 18 + 20 + 22 + 24 + 26 + 28 + 30 + 32 + 34 + 36 + 38 + 40 + 42 + 44 + 46 + 48 + 50 + 52 + 54 + 56 + 58 + 60 + 62 + 64\]

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:

\[S_n = \frac{n}{2} (a + l)\]

Substituting the values, we get:

\[S_{28} = \frac{28}{2} (10 + 64) = 14 \times 74 = 1036\]

Next, we find the average temperature by dividing the sum by the number of days:

\[\text{Average temperature} = \frac{1036}{28} = 37\]

Therefore, the average temperature for February is \(\boxed{37}\) degrees Celsius.
