Question

Select the function that defines the given sequence. -11,-8,-5,-2,1,.... A. f(1)=-11 f(n) = f(n+1) + 3; for n = 2,3,4,.... B. f(1)=-11 f(n) = f(n-1) -3; for n = 2,3,4,.... C. f(1)=-11 f(n) = f(n-1) + 3; for n = 2,3,4,.... D. f(1)=-11 f(n) = f(n+1) - 3; for n = 2,3,4,....

Answer 1

f(1) = -11

f(n) = f(n-1) +3 n=2,3,4,5

Explanation:

-11,-8,-5,-2,1,....

We are adding 3 each time

-11 +3 = -8

-8+3 = -5

f(1) = -11

Take the previous term and add 3

f(n) = f(n-1) +3 n=2,3,4,5
