Abstract :
In this paper we prove that if (r,12)less-than-or-equals, slant3, then the set of positive odd integers k such that kr−2n has at least two distinct prime factors for all positive integers n contains an infinite arithmetic progression. The same result corresponding to kr2n+1 is also true.
