  1. In the definition of the limit of a sequence, N\displaystyle {N} depends on ε\displaystyle \varepsilon.
  2. A sequence may have more than one limit.
  3. The only way to calculate the limit of a sequence is using the definition.
  4. If x\displaystyle {\left|{x}\right|} is a lower bound for {εR:ε>0}\displaystyle {\left\lbrace\varepsilon\in\mathbb{R}:\varepsilon\gt{0}\right\rbrace}, then x=0\displaystyle {x}={0}.
