In lectures we have seen that the set {1, 2, . . . , n} has 2n subsets. Now say that a set is spaced-out if it does not contain two consecutive numbers. For example, {1, 2, 3} has five spaced-out subsets: ∅, {1}, {2}, {3}, {1, 3}. How many spaced-out subsets does {1, 2, 3, 4} have? Can you guess how many spaced-out subsets {1, 2, . . . , n} has? Can you prove it?
