The passage around this formula
For naive and hybrid RAG, k = 1 by construction — the sum has exactly one term, and total latency is boundable in advance for any query. For iterative RAG, k is a small integer set by a heuristic or a step cap chosen by the system builder, so the worst case is known even though the typical case varies with question…

A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
