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=    

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

30 feet

step-by-step explanation:

that would be 2 1/2 * 12

= 24 + 6

= 30 feet   (answer)
