Question

Use function notation to write a recursive formula to represent the sequence: 4, 8, 12, …

A.f(n) = f(n − 1) + 4
B.f(n) = f(n − 1) + 2
C.f(n) = f(n − 1) ⋅ 4
D.f(n) = f(n − 1) ⋅ 2

Answer 1

Answer: A.f(n) = f(n − 1) + 4 Hope this helps :)

Answer 2

A.f(n) = f(n − 1) + 4

Explanation:

4+4 = 8

8+4 = 12

We are adding 4 to the term before it

f(n) = f(n-1) +4
