The discussion revolves around the concept of determining the limit of an array's average as the number of terms approaches infinity. Participants clarify that "array" refers to a list of numbers and "average" typically means the arithmetic mean. However, there is confusion regarding the definition of "limit" in this context, particularly what variable is being considered as it approaches infinity. The conversation emphasizes the need for precise definitions to understand the mathematical implications fully. Ultimately, the limit of an array's average can be analyzed as the number of terms increases indefinitely.
