Which best describes the relationship between the successive terms in the sequence shown? 9, –1, –11, –21, …
a.the common difference is –10.
b.the common difference is 10.
c.the common ratio is –9.
d.the common ratio is 9.2. a sequence is defined recursively using the formula f(n 1) = f(n) – 5 . which sequence could be generated using this formula?
a.1, –5, 25, –125,
b.2, 10, 50, 250,

 hello :
the arithmetic sequence 9, –1, –11, –21  has  common difference :
d = (-21)-(-11) =(-11)-(-1) = (-1)-(9) = -10

sequence is defined recursively using the formula f(n +1) = f(n) – 5 (arith -seq)
is :  C) 3, –2, –7, –12, ...
because : (-12)-(-7)=(-7)-(-2)=(-2)-(3) = -5 =  d  (common difference)
