During week 2, I learned about geometric sequences. In geometric sequences, the same number has to be multiplied into each term. The number that is being multiplied is called the common ratio. I learned how to find , the ratio, or just n.
Ex. 4, 8, 16, 32, 64, … Common Ratio = 2
Find
= a
= 4
= 4 (32,768)
= 131,072
