Algebra 2 | Unit 1 | Lesson 4: Using Technology to Work with Sequences | Practice Problems

Technology required. Open 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?

• = A1 * 2

• = A1 + 2

Technology required. Open a blank spreadsheet. In A1, type 2 and enter. What should you type into cell A2 to generate the sequence 2, 4, 6, 8, 10, . . . when you fill down the column?

• = A1 * 2

• = A1 + 2

Technology required. Open a 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?

• = A1 * 0.5

• = A1 - 75

Technology required. Open a blank spreadsheet. In A1, type 400 and enter. What should you type into cell A2 to generate the sequence 400, 325, 250, 175, 100, . . . when you fill down the column?

• = A1 * 0.5

• = A1 - 75

Technology required. Open a blank spreadsheet. If cell A1 = 5 and cell A2 = A1 * 3 + 2, what are the first 5 terms of the sequence?

• 5, 17, 53, 161, 485

• 1, 9, 33, 105, 321

• 2, 12, 42, 132, 402

Technology required. Open a blank spreadsheet. If cell A1 = 1 and cell A2 = (A1 + 2) * 3, what are the first 5 terms of the sequence?
