SUMMARY

The discussion centers on the convergence of sequences in relation to natural numbers. It is established that a sequence of real numbers can converge to a natural number, specifically x_{0}, even if none of its terms are natural numbers. An example provided is a sequence that converges to 0, which satisfies the conditions outlined in the query. The conclusion affirms that such sequences exist and can be constructed.

PREREQUISITES
  • Understanding of real number sequences
  • Knowledge of convergence in mathematical analysis
  • Familiarity with natural numbers and their properties
  • Basic concepts of limits in calculus
NEXT STEPS
  • Explore the properties of convergent sequences in real analysis
  • Study sequences that converge to specific limits, such as 0
  • Investigate the definitions and examples of limits in calculus
  • Learn about sequences that consist solely of non-natural numbers
USEFUL FOR

Mathematicians, students studying real analysis, and anyone interested in the properties of sequences and convergence in mathematical contexts.

Let x_{0} element of N. Then there is a sequence (x_{n}) that converges at x_{0} but has no terms that are nutural numbers.

Is that true?

Thank you

Welcome tp PF.

What do you mean by a sequence to converge at some point?

If you ask if a sequence of real numbers all of whose term are not natural numbers can converge to some natural number, the answer is yes. I assume, you prefer trying to prove it yourself to being given a hint right away.
 
Can you think of a sequence that converges to 0? Does that meet the requirements?
