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?

A. f(n) = 5n - 1; n ≥ 1

B. f(n) = 5n + 1; n ≥ 1

C. f(n) = 4n - 1; n ≥ 1

D. f(n) = 4n + 1; n ≥ 1

Y cant u just use +4....... :P

Answer 7

Solomon i think he is just looking for the answer

Answer 8

but we should help him

Answer 9

find the difference, that will be the "slope" of it.

Answer 10

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

Answer 11

n>=1

Answer 12

No I do not, I got c earlier

Answer 13

\(\Large \color{black}{ d=a_{n}~-~a_{(n-1)} }\)

Answer 14

first term=a=5
common difference=d=4
formula of nth term=a+(n-1)d=5+(n-1)4=4n+1:n >=1

B. The value of (7x - 1) when x = 12
C. The value of 12 f(x) when x = 12
D. The value of f(x) when (7x - 1) = 12

Answer 20

why do you ask this question??? The answer is B

Answer 21

huh?

Answer 22
