Question

Shaunta is developing a recursive formula to represent an arithmetic sequence in which 5 is added to each term to determine each successive term. Which formula could represent her sequence? f(n + 1) = f(n) + 5 f(n + 1) = f(n + 5) f(n + 1) = 5f(n) f(n + 1) = f(5n)

Answer 1

f(n+1) = f(n) +5

Explanation:

Answer 2

f(n+1) = f(n) +5

Explanation:

Since f(n) is a term, and f(n+1) is the next term, and since the next term is 5 more than the one before, you expect the formula to look like

f(n+1) = f(n) +5
