Convergent sequence

Definition

A real sequence (an)(a_n) is convergent if it converges to some real number LL. Here convergence is in the sense of the limit of a sequence.

Remarks

The sequences 1/(n+1)1/(n+1) and (n+1)/(n+2)(n+1)/(n+2) are convergent, with limits 00 and 11. The constant sequence an=ca_n = c converges to cc. A sequence that is not convergent is a divergent sequence.

Explanations

L1 human

A convergent sequence is a sequence that has a limit. Its terms settle down near one real number.

What this node needs for W1
  • an inventory row: the row of the inventory that the node accounts for (0 of 1)

The writing levels say how complete the text of a node is. They do not measure its truth.

What this needs

To read this node, read these 4 nodes in this order. The foundations come first, and the list ends with this node.

Each node uses the nodes above it. The colour of the bar on a box shows the evidence level, and the box also gives it as text. The list below has the same nodes.
