Module 3 Mid-Chapter Test Review

2
**Describe what makes a sequence Arithmetic**

Answer: Arithmetic sequences are sequences in which the terms are separated by a common difference (same number added and subtracted to each previous term). The common difference is found by subtracting the previous term.

3
**Describe what makes a sequence Geometric**

Answer: Geometric sequences are sequences in which the terms are separated by a common ratio (same number multiplied by each previous term). The common ratio is found by dividing the previous term.

4
Using the the sequence 9, 16, 23, 30.. Is the sequence Arithmetic or Geometric? Answer: Arithmetic, the same term is being added each time. What is the Common Difference? Answer: 7 What is the recursive formula for the sequence? Answer: f(n) = f(n-1) + 7 What is the explicit formula for the sequence (simplified)? Answer: f(n) = 7n + 2 What is the 67th term of this sequence? Answer: f(67) = 471

5
**Given the following sequenceβ¦**

1 2 3 4 5 6 15 37.5 93.75 Is the sequence Arithmetic or Geometric? Answer: Geometric, the previous term is being multiplied by the same number. Identify the Common Ratio? Answer: Common Ratio is 2.5 What is the Recursive formula for the sequence? Answer: f(n) = f(n-1) x 2.5 What is the Explicit Formula for the sequence? Answer: f(n) = 2.5 πβ1 x 6 What is the 13th term in the sequence? Answer: f(13) =

6
**Given the Recursive Formula f(n) = f(n-1) + 4 and f(1) = 3**

What is the 6th term of the sequence? Answer: f(6) = 23

7
**Given the Graph Is the sequence Arithmetic or Geometric**

What is the common difference or ratio 2

Johnny wants to get better grades so he decides he is going to study more. He decides that he is going to start with 15 minutes a night and increase the time by 5 minutes each night. Is the sequence Arithmetic or Geometric? Answer: Arithmetic What is the Common Difference? Answer: 5 minutes What is the Recursive formula? Answer: f(n) = f(n-1) +5 What is the Explicit Formula (Simplified)? Answer: f(n) = 5(n-1) + 15 He has 20 nights to study before the big test. How much time will he spend studying on the final night? Answer: 110 minutes or 1 hour 50 minutes
