i have a general question.is mathematics something that which already exists in nature and you people are discovering it or is it an invented concept….

]]>In Analysis I, Definition 6.4.1, a limit point is continually ε-adherent to the sequence mentioned for every ε>0.

Then using the observation under the remark 5.4.11, that the preposition 4.3.7 holds for reals, from 4.3.7 (a) and Definition 6.4.1 can we conclude that there exists a N >= m for which each n >= N the limit point is always equal to each member of the sequence for n>= N?

(In high school we were told that the sequence approaches infinitely the limit point but never “touch” it).

Thanks in advance.
