The explicit formula for the geometric sequence -1. 1 -1,3, - 9. is f(x) = -1(-3)*-1. What is the common ratio
and recursive formula for this sequence?
3; f(x + 1) = 3(f(x))
0 -3; f(x + 1) = -3(f(x))
3; f(x + 1) = {(f(x))
0 -3; fx + 1) = { 09x))

Its B

Step-by-step explanation:

I guessed and got it right the 2nd time :)

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
