Question

The first five terms of a sequence are shown below.

5, 9, 13, 17, 21

If the nth term of this sequence is represented by f(n), which of the following functions best represents this sequence?

f(n) = 5n - 1; n ≥ 1

f(n) = 5n + 1; n ≥ 1

f(n) = 4n - 1; n ≥ 1

f(n) = 4n + 1; n ≥ 1

Answer 1

Giving a medal..

Answer 2

ok

Answer 3

the letter D

Answer 4

that wht I think

Answer 5

Another....



A sequence has its first term equal to 8 and each term of the sequence is obtained by adding 6 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) = 6 and f(n) = f(n - 1) + 8; n > 1

f(1) = 8 and f(n) = f(n - 1) + 6; n > 1

f(1) = 8 and f(n) = f(n - 1) + 6n; n > 1

f(1) = 6 and f(n) = f(n - 1) + 8n; n > 1

Answer 6

huh

Answer 7

adding 6 to previous term.
previous term f(n-1)
calculate f(n)

Answer 8

Sorry im still confused

Answer 9

So what would the answer be?

Answer 10

just add6

Answer 11

Add 6 to what

Answer 12

f(1) meansfirst term

Answer 13

f(7)?

Answer 14

f(1)=first term =8
f(n)=previous term +6=f(n-1)+6

Answer 15

So what amswer would that be
