%0 Journal Article %T Three term recurrence and residue completeness %A Cheng Lien Lang %A Mong Lung Lang %J Mathematics %D 2013 %I arXiv %X We study the three term recurrence modulo m. In particular, we prove that Pell numbers modulo m is residue complete if and only m is 2, a power of 3, or a power of 5. Pell-Lucas numbers modulo m is residue complete if and only if m is a power of 3. %U http://arxiv.org/abs/1307.7463v1
