3) Here is a recursive function for sequence f: f(1)=23,f(n)=f(n−1)−7. The explicit formula for the term is f(n)=23−7(n−1). a. Explain how you know that these definitions represent the same sequence. b. Select a definition to calculate f(20), and explain why you chose it.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
