Average of an array

[kishtik]

Is limit of an array average of its terms?

[arildno]

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?

[HallsofIvy]

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.
