Discussion Overview

The discussion revolves around the concept of whether the limit of an array corresponds to the average of its terms, exploring definitions and interpretations of "limit," "average," and "array." The scope includes conceptual clarification and mathematical reasoning.

Discussion Character

  • Conceptual clarification, Debate/contested, Mathematical reasoning

Main Points Raised

  • One participant questions the meaning of "limit," asking for clarification on whether "average" refers to the arithmetic average and if "array" denotes a list of numbers like a vector or matrix.
  • Another participant expresses willingness to interpret "array" as a list of numbers and "average" as the arithmetic mean, but seeks clarification on the variable involved in determining the "limit" of the array.
  • A later reply defines the array as a function from the positive integers to the real numbers and specifies that "average" can refer to both arithmetic and geometric means, while "limit" pertains to the limit of this function as n approaches infinity.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the definitions of "limit," "average," and "array," indicating that multiple interpretations and competing views remain unresolved.

Contextual Notes

Limitations include ambiguity in the definitions of "limit," "average," and "array," as well as the lack of clarity regarding the variable approaching infinity.

Is limit of an array average of its terms?
 
Physics news on Phys.org
This is incomprehensible; what do you mean by the term "limit", is "average" arithmetic average, is "array" meant to denote an array of numbers like a vector or matrix?
 
I would be willing to assume that "array" means just a list of numbers and that "average" is the mean or arithmetic average but I still have no idea what you mean by the "limit" of an array. The limit as what variable goes to what?
 
Sorry!
Suppose (an)=(a1, a2, ..., an) is a function from N+ to R ("array"), "average" can be both arithmetic and geometric, "limit" is the limit of this function while n->infinity.
