In his proof of the irrationality of  $\zeta (3)$ and
$\zeta (3)$ and  $\zeta (2)$, Apéry defined two integer sequences through
$\zeta (2)$, Apéry defined two integer sequences through  $3$-term recurrences, which are known as the famous Apéry numbers. Zagier, Almkvist–Zudilin, and Cooper successively introduced the other
$3$-term recurrences, which are known as the famous Apéry numbers. Zagier, Almkvist–Zudilin, and Cooper successively introduced the other  $13$ sporadic sequences through variants of Apéry’s

$15$ Apéry-like sequences  $\{u_n\}_{n\ge 0}$. Let
$\{u_n\}_{n\ge 0}$. Let  $N_{\alpha }$ be the largest positive integer such that
$N_{\alpha }$ be the largest positive integer such that  $u_n\equiv \alpha ^n\ \pmod {N_{\alpha }}$ for all non-negative integers n. We determine the values of

$15$ Apéry-like sequences  $\{u_n\}_{n\ge 0}$. The binomial transforms of Apéry-like sequences provide us a unified approach to this type of congruences for Apéry-like sequences.
