Finite Sequences
Section 12.3 Date _________ Period _______
Show that each of the following sequences are geometric by solving for the common ratio (see first problem as an example). Then, write out the first four terms.
1) [pic] 2) [pic]
3) [pic] 4) [pic]
5) [pic] 6) [pic]
Determine whether the following sequences are arithmetic, geometric, or neither. If the sequence is arithmetic, find the common difference; if it is geometric, find the common ratio.
7) [pic] 8) [pic] 9) [pic]
10) 1, 3, 6, 10, . . . 11) 1, 1, 2, 3, 5, 8, . . . 12) [pic]
For the following problems, find the fifth term and [pic], the [pic] term, of the geometric sequence whose initial term a and common ratio r are given.
13) [pic] 14) [pic] 15) [pic]
Find the indicated term of each of the following geometric sequences.
16) 7th term of [pic] 17) 8th term of 1, 3, 9, . . .
18) 10th term of -1, 2, -4, . . . 19) 8th term of 0.4, 0.04, 0.004, . . .
20) You are interviewing for a job and receive two offers:
A: $20,000 to start, with guaranteed annual increases of 6% for the first 5 years.
B: $22,000 to start, with guaranteed annual increases of 3% for the first 5 years.
Which offer is best if your goal is to be making as much as possible after 5 years?
Which is best if your goal is to make as much money as possible over the life of the contract (5 years)?
