Subsequence

Summary

A subsequence of a sequence keeps infinitely many of its terms, in their original order. Subsequences are the main tool of the Bolzano–Weierstrass theorem. The node subsequence gives the precise definition.

What this node needs for W2
  • edge instance_of in: at least two examples (0 of 2)
  • edge not_instance_of in: at least one non-example (0 of 1)
  • edge specializes both: the more general notions and the special cases (0 of 1)

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