Patterns are repetition of different terms, but the each term is built on previous term. Patterns are often growing. For example, 2, 4, 6, 8, 10. . . and 1, 2, 4, 8, 16. . . are two common increasing patterns. Using a table to model an increasing/decreasing pattern can help students organize their thinking. It can also help them generalize the patterns symbolically.
