We also have functions to generate lists (sets of even numbers and odd numbers from N). • even = 2 → 0,2,4,6… • odd = 2 + 1 → 1,3,5,7… • ∪ = , ∩ = ∅ • Definition-‐ A sequence is a set of numbers written in some particular order. Sequences can be finite and infinite. • (Rosen) Definition-‐ A sequence is a function from a subset of
