Sequences Q: Write an equation for a geometric sequence that starts with 82 and decreases by 14 each time. A: t(n) = 82 - 14(n - 1)
Sequences Q: A:
Sequences Q: What kind of graphs do sequences have? A: Discrete
Sequences Q: How are is the domain of a sequence restricted? A: The input value is n, the natural numbers, whole numbers greater than zero.
Sequences Q: True or false, terms can have decimal values? A: True, an example : 7, 10.5, 14, 17.5, 21, ...
Sequences Q: True or false, all sequences have y-intercepts? A: False, no sequences have y-intercepts.
Sequences Q: What is the difference between arithmetic and geometric sequences? A: Arithmetic grow by addition and geometric grow by multiplication.
Sequences Q: True or false, decimals are part of the domain of sequences? A: False, only whole numbers greater than zero are in the domain of sequences.
Sequences Q: Describe the rule for the sequence 5, 9, 9, 5, 9, 9,... A: It starts with 5, 9 twice, then 5, repeat.
Sequences Q: What functions are like geometric sequences? A: Exponential
Sequences Q:Describe the rule for the sequence 73, 63, 53, 43, ... A: It starts with 73 and decreases by subtracting 10 each time.
Sequences Q: What information is necessary for writing a rule for a sequence? A: You must have the starting point and growth (generator).
Sequences Q: Describe the rule for the sequence 256, 128, 64, 32, 16, ...? A: The initial value is 256, it divides by 2 each time.
Sequences Q: What is the initial value of an arithmetic sequence if t₃ = 20 and t₄ = 22? A: the initial value is 16, t₁ = 16, t(1) = 16
Sequences Q: What functions are like arithmetic sequences? A: Linear
Sequences Q: What is the missing term in this sequence 2, 6, 18, ____, 162, ...? A: 54
Sequences Q: Describe the rule for the sequence 16, 21, 26, 31, 36, ... A: The initial value is 16 and it grows by adding five each time.
Sequences Q: What is the missing term in this sequence, 15, 18, 21, ___, 27...? A: 24
Sequences Q: True or false, all sequences are arithmetic or geometric. A: False, there are all kinds of sequences.
Sequences Q: What is the missing term in this sequence, n, 3n, 9n, ____, 81n. A: 27n
Sequences Q: What is the third term of t(n) = 5(2^(n - 1)) A: 20
Sequences Q: What is the third term of t(n) = 12 - 5(n - 1) A: 2
Sequences Q: What kind of sequence is this, 6, 12, 24, 48, ...? A:Geometric because it multiplies by 2
Sequences Q: What kind of sequence is this, 92, 88, 84, 80, ... A:Arithmetic because it decreases by subtracting four each time.
Sequences Q: Describe the rule for the sequence 24, 23, 24, 27,... A: It starts with 24 and increases by consecutive odd numbers.
Sequences Q: Write an equation for an arithmetic sequence that starts with 12 and increases by 7 each time. A: t(n) = 12 + 7(n - 1)
