Question

a sequence has its first term equal to 3, and each term of the sequence is obtained by adding 5 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) = 3 and f(n) = f(n - 1) + 5; n > 1
f(1) = 5 and f(n) = f(n - 1) + 3; n > 1
f(1) = 3 and f(n) = f(n - 1) + 5n; n > 1
f(1) = 5 and f(n) = f(n - 1) + 3n; n > 1 @hartnn

Answer 1

first term =3
so f(1) =3

Answer 2

because f(n) denotes n'th term

Answer 3

next term = previous term +5

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

Answer 4

wats the 2nd part

Answer 5

so its a

Answer 6

A

Answer 7

yes :)
