Discrete mathmatics please solve all my question

4. What are the terms ao, a1, a2, and a3 of the sequence (an), where an equals b) 3? d) 2"(-2)"? c) 7+4"? n2 10. Find the first six terms of the sequence defined by each of these recurrence relations and initial conditions. 16. Find the solution to each of these recurrence relations with the given initial conditions. Use an iterative approach such as that used in Example 10. 18. A person deposits $1000 in an account that yields 9% interest compounded annually a) Set up a recurrence relation for the amount in the ac- count at the end of n years. Find an explicit formula for the amount in the account at the end of n years. b) c) How much money will the account contain after 100 years
