👉 The term "athetotic" is a term used in the context of mathematics, specifically in the field of number theory. It refers to an arithmetic progression where each term after the first one equals the previous one plus a constant value. In other words, if we have an arithmetic progression with the initial term \(a_1\), the common difference \(d\) between successive terms, and the last term \(\text{last}\) as given by: \[a_n = a_1
