Sequences True or False

1.	An arithmetic sequence is a sequence where -> the difference of successive terms is constant. True False
2.	The sequence -1, -1, -1, -1,... is -> both arithmetic and geometric True False
3.	The sequence 0, -3, -6, -9, ... is -> arithmetic only. True False
4.	The sequence 60, -30, 15, -7.5,... is -> geometric with True False
5.	An arithmetic sequence has a₁ = 5 and d = 9. What is a₂₅? -> 221 True False
6.	An arithmetic sequence has a₁₁ = 4.54 and a₂₀ = 9.04. Find a₁ and d. -> d = 0.5 and a₁ = -0.46 True False
7.	A geometric sequence has a = 100,000 and r = 0.2. Find a₁₀. -> 0.0512 True False
8.	A geometric sequence has a₅ = c and a₁₀ = d. Which of the following is true? -> True False
9.	In a geometric sequence, the general term is given by -> a_n = a₁r^{n + 1} True False
10.	An arithmetic sequence has a₈ = 9.5 and a₉ = 9.75. What is a₂? -> 7.75 True False
