1. Số số hạng của dãy:
   \(\text{(S\ cui\ -\ S\ đu)\ :\ Khong\ cách\ +\ 1}=(100-1):1+1=100\text{\ (s\ hng)}\)
2. Tổng của dãy số:
   \(\text{S}=\frac{(\text{S\ đu\ +\ S\ cui})\times \text{S\ s\ hng}}{2}\)
   \(\text{S}=\frac{(1+100)\times 100}{2}=\frac{101\times 100}{2}=5050\)

• Phép tính 1: \(27015 + 13569 - 2468 = 38116\)
• Phép tính 2: \(49091 - 32728 : 4 = 49091 - 8182 = 40909\)

• Điều này xảy ra khi toàn bộ nhóm học sinh ít hơn nằm trong nhóm học sinh đông hơn.
• Cụ thể: Tất cả \(20\) học sinh biết chơi bóng rổ đều biết chơi cả cầu lông.
• Khi đó, tổng số học sinh lớp 6A chính bằng số học sinh biết chơi cầu lông.

Số học sinh ít nhất là: \(25\) học sinh.

• Theo đề bài: "Tất cả học sinh lớp 6A đều biết chơi bóng rổ hoặc cầu lông", nhưng không bắt buộc phải có người chơi cả hai.
• Trường hợp này xảy ra khi không có học sinh nào biết chơi cả hai môn (hai nhóm riêng biệt hoàn toàn).
• Tổng số học sinh = (Số HS chơi bóng rổ) + (Số HS chơi cầu lông).
• Tính toán: \(20 + 25 = 45\).

Số học sinh nhiều nhất là: \(45\) học sinh.

My Peaceful Countryside: A Place Called HomeWhile many people are drawn to the glittering lights and constant hustle of big cities, I find my heart belongs to the serene and simple beauty of the countryside. I was born and raised in a small rural village, a place where time seems to slow down and nature dictates the rhythm of life. To me, the countryside is not just a geographic location; it is a sanctuary of peace, tradition, and community.The Natural LandscapeThe first thing that strikes anyone visiting my village is the overwhelming presence of greenery. Unlike the concrete jungles of urban areas, my home is surrounded by vast, emerald-green rice fields that stretch as far as the eye can see. Depending on the season, these fields transform from a vibrant green to a shimmering golden yellow during harvest time. The scent of ripening rice, mixed with the earthy aroma of the soil after a rain shower, is a fragrance that no expensive perfume can replicate.Running through the heart of the village is a small, winding river. Its water is clear enough to see the pebbles at the bottom and the small fish swimming against the current. This river is the soul of our village, providing water for the crops and a playground for the local children during hot summer afternoons. The air here is incredibly fresh and pure, free from the exhaust fumes and industrial pollutants of the city. Waking up to the sound of birds chirping and the gentle rustle of leaves is a far better alarm clock than the blaring horns of traffic.The Pace of Life and PeopleLife in the countryside is characterized by its simplicity and tranquility. People here do not live by the strict, stressful schedules often found in cities. Instead, life follows the sun and the seasons. Farmers head to the fields at dawn and return as the sun sets, their faces etched with the honest fatigue of hard work but always carrying a smile.What truly makes my village special, however, is the sense of community. In the city, you might not even know your next-door neighbor's name. In my village, everyone knows everyone. There is a profound sense of "neighborliness" where people genuinely care for one another. If someone is building a house or harvesting a crop, the neighbors will naturally drop by to lend a hand. We share our joys and our sorrows. During traditional festivals, the entire village gathers at the communal house to pray for a good harvest and enjoy traditional music and games. This bond creates a safety net of emotional support that is rare in modern society.The Charm of TraditionLiving in the countryside allows one to stay connected with cultural roots. Many ancient traditions are still preserved here. You can still see old banyan trees, wells, and communal houses which have stood for centuries. The lifestyle is deeply rooted in agriculture, and the festivals often revolve around thanking nature for its bounty. This connection to the past gives us a sense of identity and belonging.Challenges and the FutureOf course, life in the rural areas is not without its challenges. Access to high-end healthcare, advanced education, and diverse entertainment options is more limited than in urban centers. Many young people leave for the cities in search of better career opportunities. However, in recent years, there has been a shift. With the improvement of infrastructure and the internet, the gap between the city and the country is narrowing. More people are beginning to appreciate the "slow life" and the mental health benefits of living close to nature.ConclusionIn conclusion, the countryside is a place of immense beauty and spiritual richness. It offers a quality of life that prioritizes peace, health, and human connection over material gain and speed. Whenever I return home after a long trip, the sight of the familiar bamboo groves and the quiet atmosphere immediately washes away my stress. It is a place that reminds me of who I am and what truly matters in life. No matter where my path leads me in the future, the peaceful fields of my village will always be the place I call home.
