2. If an n → ∞, then no closer to any real number equal to or not. The sequence is the sequence to be called Dai woechen (divergent sequence). And there is no limit, then the sequence is called a fade out.
2. If n → ∞ then an approach does not equal any real number to call that number. Convergent sequence (divergent sequence) and a sequence that has no limits or the sequence divergence.
2. If n - > ∞ and an not approach or equal to any real numberCall sequence that sequence arithmetic (divergent sequence).And the no limit or called sequence is divergent.
