6-29.

For each recursively-defined sequence below, write the first few terms. Then use the terms to write an explicit equation. Homework Help ✎

*a*_{1}= 17

*a*_{n}_{+1}=*a*– 3_{n}*a*_{1}= 20

*a*_{n}_{+1}=· *a*_{n}

For help, write out a sequence:*a*_{1} = 17, *a*_{2} = 14, and so on.

*a _{n}* = 20 − 3

*n*

*a*_{1} = 20, *a*_{2} = 10, and so on.
