The purpose of this paper is (1) to present how general education elementary school age students constructed computer passwords using digital root sums and second-order arithmetic sequences, (2) argue that computer password construction can be used as an engaging introduction to generate interest in...
Sometimes, sequences build on the number immediately before it. For example, with the sequence 2, 4, 6, 8,..., each term is found by adding two to the previous term. When a sequence is built by adding a constant number to the previous term, that is called an arithmetic sequence.View...
