One hundred and nine is the answer
Answer:
29
Step-by-step explanation:
it's arithmetic sequence.
it has a basic equation like this
Un = a + (n-1)d
a = U1 = first number in sequence
Un = number in n-th term
d = difference
U9 = 101 + (9-1)(-9)
U9 = 101 - 72
U9 = 29
so the 9th term is 29
(4, 1), (1, -3), and (2,0)
