Enter the explicit rule for the geometric sequence. 14,12,1,2,4,…

an =

Step-by-step explanation:

Explicit rule for Geometric series is given by

Here a is the first term and r is the common ratio.

in our question  first term a =

common ratio r = 2

therefore explicit rule an =

                                 or

                              an=    

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
