From the given geometric sequence find r the common ratio
r =
=
= - 4
Hence recursive rule is
= - 4

Question
---------------------------------------------------
x² - 49
--------------------------------------------------
Form into 2 perfect squares
---------------------------------------------------
x² - 7²
--------------------------------------------------
Formula
---------------------------------------------------
a² - b² = (a + b) (a - b)
--------------------------------------------------
Apply the formula
---------------------------------------------------
x² - 7² = (x + 7)(x - 7)
--------------------------------------------------
Answer: (x + 7)(x - 7)
