A sequence is shown in the graph. (1,6) 2 (2, 3) (3, 1.5) (4, 0.75)

2. Write the first five terms of each sequence. Determine whether each sequence is arith geometric, or neither. Note: a(1) = 7 means that the first term of the sequence is 7. a. a(1) = 7,a(n) = a(n – 1) – 3 for n22. This sequence is The first five terms are 7, , and b. b(1) = 2,b(n) = 2-b(n - 1) – 1 for nz2. This sequence is The first five terms are and c. c(1) = 3,c(n) = 10-c(n – 1) for n22. This sequence is The first five terms are and d. d(1) = 1,d(n) = n· d(n – 1) for n22. This sequence is The first five terms are and 1 D00 F4 F5 F10 % & * 5 6 7 8 9
