Which recursive formula can be used to generate the sequence shown, where f(1) = 9.6 and n > 1? 9.6, –4.8, 2.4, –1.2, 0.6,

Recursive formula will be

Step-by-step explanation:

The given sequence is 9.6, -4.8, 2.4, -1.2, 0.6......

In this sequence we find that there is a common ratio which makes this sequence a geometric sequence.

For a geometric sequence explicit formula is given by

if n > 1

So by putting values of a = 9.6

and common ratio r = =

Therefore, the recursive formula will be

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
