Unit 1, Lesson 4
Using Technology to Work with Sequences
Algebra 2
Practice
Problem 1
Technology required. Open a blank spreadsheet. In A1, type “2” and hit Enter.
- What should you type into cell A2 to generate the sequence 2, 4, 8, 16, 32, . . . when you fill down the column?
- What should you type into cell A2 to generate the sequence 2, 4, 6, 8, 10, . . . when you fill down the column?
Problem 2
Technology required. Open a blank spreadsheet. In A1, type “400” and hit Enter.
- What should you type into cell A2 to generate the sequence 400, 200, 100, 50, 25, . . . when you fill down the column?
- What should you type into cell A2 to generate the sequence 400, 325, 250, 175, 100, . . . when you fill down the column?
Problem 3
Technology required. Open a blank spreadsheet.
- If cell A1 is 5 and cell A2 is = A1 * 3 + 2, what are the first 5 terms of the sequence?
- If cell A1 is 1 and cell A2 is = (A1 + 2) * 3, what are the first 5 terms of the sequence?
- If cell A1 is 2 and cell A2 is = (A1 + 2) * 3, what are the first 5 terms of the sequence?
