Lesson 250 of 1524
4.16 Introducing Arithmetic Sequences
Consider the function f given by f ( n ) = 3 n - 7 .
Practice this chapterConsider the function f given by f ( n ) = 3 n - 7 . This function takes an input, multiplies it by 3, and then subtracts 7
For each sequence, describe a way to produce a new term from the previous term
Be able to explain what it means for a sequence to be arithmetic or geometric.
Worked example
What does this chapter state?
- 1Consider the function f given by f ( n ) = 3 n - 7 .
- 2That claim is the chapter’s own statement.
- 3Answer from the claim, not from where the chapter sits in the book.
Result: Consider the function f given by f ( n ) = 3 n - 7 .
Why. The sentence is taken from this chapter’s summary or key concepts.
Answer with the meaning this chapter gives. A nearby idea from the same book is a different term.
