4. The sequence 4.9,15,21,27,\ldots is an arithmetic sequence with a common difference of 6. The recursive formula for this sequence is a_n = a_{n-1} + 6, where a_1 = 9. The explicit formula for this sequence is a_n = 6n + 3.
5. The sequence 1.5,2.25,3,3.75,\ldots is an arithmetic sequence with a common difference of 0.75. The recursive formula for this sequence is a_n = a_{n-1} + 0.75, where a_1 = 1.5. The explicit formula for this sequence is a_n = 0.75n + 0.75.
6. The sequence 7,0,-7,-14 is an arithmetic sequence with a common difference of -7. The recursive formula for this sequence is a_n = a_{n-1} - 7, where a_1 = 7. The explicit formula for this sequence is a_n = -7n + 14.
