A **divisibility sequence** is a sequence of integers \\( (a_n) \\) where each term divides the subsequent terms in the sequence according to specific criteria. More formally, a sequence \\( (a_n) \\) is called a divisibility sequence if for each pair of indices \\( m \< n \\), the term \\( a_m \\) divides \\( a_n \\) (denoted as \\( a_m \\mid a_n \\)).
