Limit of a Sequence

The following figures show what is meant by the Limit of a Sequence. Scroll down the page for more examples and solutions.

The Limit of a Sequence
The concept of determining if sequence converges or diverges.
Example:
Consider the following graphs of sequences.
Do they appear to have a limit?
a_n = {1 + 1/n}
a_n = {2(-1)ⁿ/n}
Determine if the sequence converges or diverges.
a_n = (3n - 2)/(n - 1)
a_n = -2 + (-1)ⁿ
a_n = ln(n)/5n
a_n = 1/(-2)ⁿ
