2. Number Sequence
list of numbers (terms) in a specific order (not just a set) usually defined by a rule that uses positive integers description: starts at 0, each term is the sum of the previous term and the next consecutive positive integer next two terms: 15, 21 description: starts at 33, each term is 3 less than the previous term next two terms: 21, 18 What form of reasoning is used to develop an idea for the pattern? Which sequence is arithmetic?
