Question

PLEASEE HELLPP!!!!

Enter the first 4 terms of the sequence defined by the rule given.

f(1) = 8, f(n) = f(n − 1) − 4


The first 4 terms are.....

Answer 1

fn-32/fn=0

Explanation:

f(n-1)-4=fn

(fn-f1)-4=fn

(fn-8)-4

fn-32=fn

fn fn

fn-32/fn=0

Answer 2

8, 4, 0, - 4

Explanation:

Using the rule and f(1) = 8, then

f(2) = f(1) - 4 = 8 - 4 = 4

f(3) = f(2) - 4 = 4 - 4 = 0

f(4) = f(3) - 4 = 0 - 4 = - 4

The first 4 terms are 8, 4, 0, - 4
