The boundedness of a sequence refers to the property of the sequence where its values are limited within a certain range. A sequence is said to be bounded if there exists a real number M such that the absolute value of each term in the sequence is less than or equal to M. In other words, a sequence is bounded if its terms do not grow infinitely large or small as n approaches infinity. **

The boundedness of a sequence is determined by finding a number M such that the absolute value of each term in the sequence is less than or equal to M. If such a number M exists, then the sequence is bounded. In other words, a sequence is bounded if its terms do not become arbitrarily large as n increases. If the terms of the sequence do become arbitrarily large, then the sequence is unbounded. **

To investigate the monotony of a mathematical sequence, one can analyze the signs of the differences between consecutive terms. If the differences are always positive or always negative, the sequence is monotonous. To investigate boundedness, one can analyze the values of the terms in the sequence and determine if they are limited within a certain range. If the terms do not exceed a certain value, the sequence is bounded. Combining these analyses can help determine both the monotony and boundedness of a mathematical sequence. **

Yes, the boundedness of Bn cannot be dispensed with. This is because the boundedness of Bn is essential for ensuring that the sequence of functions {Bn} converges uniformly. Without boundedness, the sequence may not converge uniformly, leading to potential issues with the convergence of the series. Additionally, boundedness is necessary for applying certain theorems and techniques in analysis, such as the Arzelà–Ascoli theorem, which requires the functions to be uniformly bounded. Therefore, the boundedness of Bn is a crucial property that cannot be ignored. **

The boundedness of Bn cannot be dispensed with because it is a crucial property that ensures the convergence of the sequence. Without boundedness, the sequence Bn could potentially grow without limit, leading to divergence. By maintaining boundedness, we can guarantee that the sequence remains within a certain range, allowing us to make meaningful conclusions about its behavior and convergence. Therefore, the boundedness of Bn is essential for establishing the convergence of the sequence. **

The limit of a sequence refers to the value that the terms of the sequence approach as the index goes to infinity. In other words, it is the value that the terms get arbitrarily close to as the sequence progresses. On the other hand, the boundedness of a sequence refers to whether the terms of the sequence are limited in their range, i.e., whether there exists a number M such that all terms of the sequence are less than or equal to M in absolute value. In summary, the limit of a sequence focuses on the behavior of the terms as the sequence progresses, while the boundedness of a sequence focuses on the range of the terms. **

The popularity of cycling or skiing can vary depending on the location and time of year. In general, cycling tends to be more popular in urban areas and during the warmer months, while skiing is more popular in mountainous regions and during the winter. However, it's difficult to determine which activity is followed more overall without specific data on participation rates in different regions and seasons. **

Convergence refers to a sequence or function approaching a specific value as the input approaches a certain point. A limit is the value that a function or sequence approaches as the input approaches a specific value. Boundedness refers to a function or sequence that does not exceed a certain value. For a straight line, there is no limit of infinity as the function does not approach a specific value as the input approaches a certain point. Straight lines have a constant slope and do not approach a specific value as the input approaches infinity. **
