I need the correct answer

Problem 5 Match each recursive definition with one of the sequences. A: 1: h(1) = 1, h(n) = 2 . h(n - 1) + 1 for 80, 40, 20, 10, 5 n 2 2: B: 1, 2, 4, 8, 16 p(1) = 1, p(n) = 2 . p(n - 1) for 3: n 2 1, 3, 7, 15, 31 C: a(1) = 80, a(n) = = . a(n - 1) for n 2 (From Unit 1, Lesson 5.) Problem 6 For each sequence, decide whether it could be arithmetic, geometric, or neither. 1. 25, 5, 1 , ... 2. 25, 19, 13, . .. 3. 4, 9, 16, ... 4. 50, 60, 70, . .. 5. 2 , 3, 18 , ... For each sequence that is neither arithmetic nor geometric, how can you change a single number to make it an arithmetic sequence? A geometric sequence
