Ext. What could the method be for describing geometric sequences? Main 1: how geometric sequences differ to arithmetic sequences What was the method we used to describe arithmetic sequences (those we saw the past few lessons)? Ext. What could the method be for describing geometric sequences?

Arithmetic Sequences: Main 1: how geometric sequences differ to arithmetic sequences Arithmetic Sequences: nth term: 𝑢 𝑛 = 𝑢 1 + 𝑛−1 𝑑 common difference: 𝑑= 𝑢 𝑛+1 − 𝑢 𝑛 Geometric Sequences: nth term: 𝑢 𝑛 = 𝑢 1 𝑟 𝑛−1 common ratio: 𝑟= 𝑢 𝑛+1 𝑢 𝑛
