Question

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.

Answer 1

D an=an-1 + 2, a1=8 hope that helps

Answer 2

The recursive formula to model Kendyl's progress is:

Fourth option: an=an-1 + 2, a1=8

Explanation:

She currently has the first eight bars memorized: The first value is 8:

a1=8

She plans to memorize two more bars everyday until she has the whole piece memorized:

The number of bars memorized is two more than the last day:

an=an-1 + 2

Then, the recursive formula is:

an=an-1 + 2, a1=8
