1. List the first 9 terms of the sequence defined recursively by = −2 ∙(−1 −1), with 1 = 2 and 2 = 3 2. Compute the value of ∑ 8^ =1> , where is the same sequence as in the previous question.

3. Is the sequence from question 1 arithmetic, geometric, or neither? Explain how you reach your conclusion.

4. Find the sum of the first 200 terms of the arithmetic sequence that begins: 12, 18, 24, …

5. Find the sum of the first 8 terms of the geometric sequence that begins: 12, 18, 27, …

6. Find the sum of the infinite geometric sequence that begins 1/12 ,1/18

,1/27 , ...

Perform the required operations on the following functions given: f(x)= 3-x; g(x)= -2x find g[f(x)]

Which value would be a solution for x in the inequality 47-4x< 7

If your score on your next statistics test is converted to a z score, which of these z scores would you prefer: minus2.00, minus1.00, 0, 1.00, 2.00? why? a. the z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores. b. the z score of 0 is most preferable because it corresponds to a test score equal to the mean. c. the z score of minus2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores. d. the z score of minus1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average
