text: In this section we give formulas for generating functions enumerating the sequence { f a n + b } {\displaystyle \{f_{an+b}\}} given an ordinary generating function F ( z ) {\displaystyle F(z)} where a , b ∈ N {\displaystyle a,b\in \mathbb {N} } , a ≥ 2 {\displaystyle a\geq 2} , and 0 ≤ b < a {\displaystyle 0\leq b<a} (see the main article on transformations).
