IM Alg2.1.4 Practice: Using Technology to Work with Sequences

Here you have a blank spreadsheet. In A1, type 2 and enter.
What should you type into cell A2 to generate the sequence 2, 4, 8, 16, 32, . . . when you fill down the column?[br]
What should you type into cell A2 to generate the sequence 2, 4, 6, 8, 10, . . . when you fill down the column?[br]
Here you have another blank spreadsheet. In A1, type 400 and enter.
What should you type into cell A2 to generate the sequence 400, 200, 100, 50, 25, . . . when you fill down the column?[br]
What should you type into cell A2 to generate the sequence 400, 325, 250, 175, 100, . . . when you fill down the column?[br]
Here you have another blank spreadsheet.
If cell A1 = 5 and cell A2 = A1 * 3 + 2, what are the first 5 terms of the sequence?[br]
If cell A1 = 1 and cell A2 = (A1 + 2) * 3, what are the first 5 terms of the sequence?[br]
If cell A1 = 2 and cell A2 = (A1 + 2) * 3, what are the first 5 terms of the sequence?[br]
Here you have another blank spreadsheet.
Find the first 5 terms of a geometric sequence that starts with -5 and has a growth factor of -1.[br]
Find the first 5 terms of a geometric sequence that starts with -20 and has a growth factor of 0.5.[br]
Find the first 5 terms of an arithmetic sequence that starts with -20 and has an rate of change of 5.[br]
Find the first 5 terms of an arithmetic sequence that starts with 43 and has an rate of change of -7.[br]
Here is the graph of a sequence.
Explain how you know this sequence is arithmetic.[br]
Explain how you know this sequence is not geometric.[br]
The first two terms of a geometric sequence are 6 and 3.
Explain why there is only one geometric sequence with these first two terms.[br]
What are the next 3 terms of this geometric sequence?[br]
