Question

A sequence has its first term equal to 4 and each term of the sequence is obtained by adding 2 to the previous term. If f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence?

f(1) = 2 and f(n) = f(n - 1) + 4; n > 1

f(1) = 4 and f(n) = f(n - 1) + 2n; n > 1

f(1) = 2 and f(n) = f(n - 1) + 4n; n > 1

f(1) = 4 and f(n) = f(n - 1) + 2; n > 1

Answer 1

first term equal to 4

Answer 2

that gives f(1) = 4

Answer 3

each term of the sequence is obtained by adding 2 to the previous term.

gives


f(n) = f(n-1) + 2

Answer 4

Would it be D? :)

Answer 5
