FAQs on Limit of a Sequence Video Lecture - IIT JAM

1. What is the definition of a limit of a sequence?
Ans. The limit of a sequence is a value that the terms of the sequence approach as the index of the sequence increases indefinitely. In other words, it is the value that the terms of the sequence get arbitrarily close to as the sequence progresses.
2. How is the limit of a sequence calculated?
Ans. The limit of a sequence can be calculated by observing the pattern of the terms of the sequence and determining the value to which they converge. This can be done analytically by finding a formula or expression for the terms of the sequence, or it can be done graphically by plotting the terms on a graph and observing the trend.
3. Is the limit of a sequence always a finite number?
Ans. No, the limit of a sequence does not always have to be a finite number. It can also be infinity or negative infinity. If the terms of the sequence become arbitrarily large as the index increases, the limit can be infinity. Similarly, if the terms become arbitrarily small (but not zero), the limit can be negative infinity.
4. Can a sequence have multiple limits?
Ans. No, a sequence can have at most one limit. If a sequence has multiple limits, it is said to be divergent and does not converge to a specific value. In other words, the terms of the sequence do not approach a single value as the sequence progresses.
5. How is the concept of limits of sequences related to the IIT JAM exam?
Ans. The concept of limits of sequences is an important topic in the mathematics syllabus of the IIT JAM exam. Understanding the properties and calculations of limits of sequences is crucial for solving problems related to calculus, real analysis, and mathematical analysis, which are common topics in the exam. Mastery of this concept is essential for success in the exam and in further studies in mathematics.
