7-48.

For parts (a) and (b), write a recursive equation using notation for each sequence. For parts (c) and (d), write an explicit equation using

*notation for each sequence. (For a reminder about sequence notation, see the Math Notes box in Lesson 5.3.2.)*

Read Math Notes box in Lesson 5.3.3 on equations for sequences.

Is the sequence arithmetic or geometric?

Remember to write an explicit equation.
