Kendyl is memorizing a piece of saxophone music to perform at a local festival. she currently has the first eight bars memorized and plans to memorize two more bars everyday until she has the whole piece memorized. write a recursive formula to model kendyl's progress.

a. a_n=2a_(n-1) ; a_1=8
b. a_n=a_(n-1)+2 ; a_1=6
c. a_n= 6+2_n ; a_1=8
d. a_n=a_(n-1)+2 ; a_1=8

Step-by-step explanation:

Given: Kendyl is memorizing a piece of saxophone music to perform at a local festival.

Let n be the total number of days.

Since she currently has the first eight bars memorized , thus

and she plans to memorize two more bars everyday .

Then, the recursive formula to model Kendyl's progress will be

, where is the total number of bars she memorized at nth day.
