SUMMARY

The sequence defined by the recurrence relation e_{n+1} = (e_n - 2) / (e_n + 4) converges to 0 under the conditions that e_0 > -1 and -2 < e_0 < -1. The proof involves demonstrating that the sequence is bounded and monotonic, leading to the conclusion that it approaches the limit of 0. The discussion emphasizes the importance of initial conditions in determining the behavior of the sequence.

PREREQUISITES
  • Understanding of recurrence relations
  • Basic knowledge of limits and convergence
  • Familiarity with sequences and their properties
  • Ability to perform algebraic manipulations
NEXT STEPS
  • Study the properties of bounded and monotonic sequences
  • Learn about convergence criteria for sequences
  • Explore examples of recurrence relations and their limits
  • Investigate the implications of initial conditions on sequence behavior
USEFUL FOR

Students of mathematics, particularly those studying sequences and limits, as well as educators looking to enhance their understanding of convergence in recursive sequences.

e_{n+1} = (e_n-2)/(e_n+4)

Prove that {e_n} converges to 0 if

(a) e_0 > -1

(b) -2 < e_0 < -1

PS: I haven't learned things like sup and inf yet, so please don't use them.
