Pattern 3: Sample Sequence: 1, 5, 13, 26, 45, 71 Recursive Formula: 7(?) = 22(?7 - 1) = (7 - 2) + 7 + 1 *Note for recursive pattern 3, be mindful of your base cases, and always know that you have the option of passing in an empty list to a recursive call. While the tricky part of this pattern can be solved with a little tinkering, we encourage you to understand exactly how the list is being built
