Under sufficiently strong assumptions about the first term in an arithmetic progression, we prove that for any integer $a$ , there are infinitely many $n\,\in \,\mathbb{N}$ such that for each prime factor $p\,\text{ }\!\!|\!\!\text{ }\,n$ , we have $p\,-\,a\,\text{ }\!\!|\!\!\text{ }\,n\,-\,a$ . This can be seen as a generalization of Carmichael numbers, which are integers $n$ such that $p\,-\,1\,\text{ }\!\!|\!\!\text{ }\,n\,-\,1$ for every $p\,\text{ }\!\!|\!\!\text{ }\,n$ .
