𝒏(𝒏+𝟏)/2∈Ω(𝒏)
This statement, n(n+1)/2 ∈ Ω(n), implies that n(n+1)/2 has a lower bound of n (in terms of growth rate), meaning that the function's growth is at least as fast as n. This statement is true because n(n+1)/2 is a quadratic function and its growth rate should be at least linear. However, this statement does not provide the full picture of the function's behavior as the equivalent growth rate of this function is actually n², as shown by the statement n(n+1)/2 ∈ Θ(n²).
