SUMMARY

The sequence defined by a = [1+(2/n)]^n converges to e^2 as n approaches infinity. This conclusion is based on the established limit definition of the mathematical constant e, where e = lim[1+1/n]^n. The initial assumption that the limit would be 1 is incorrect, as the correct evaluation of the limit reveals the exponential growth factor of 2 in the sequence. This problem exemplifies a classic limit scenario in calculus.

PREREQUISITES
  • Understanding of limits in calculus
  • Familiarity with the definition of the mathematical constant e
  • Knowledge of exponential functions and their properties
  • Basic algebraic manipulation skills
NEXT STEPS
  • Study the derivation of the limit definition of e
  • Explore other sequences that converge to e, such as lim[1+1/n]^n
  • Learn about the application of L'Hôpital's Rule in evaluating limits
  • Investigate the concept of convergence and divergence in sequences
USEFUL FOR

Students studying calculus, mathematics educators, and anyone seeking to deepen their understanding of limits and convergence in sequences.

Homework Statement



Determine whether the following sequence converges or diverges. If converges, find the limit:

a = [1+(2/n)]^n


Homework Equations




The Attempt at a Solution



I thought the limit would be one as inside the brackets at infinity it would be 1^n which would equal 1

*the answer given at the back of the book is e^2
