Answer:
4 n - 7
Explanation:
- 3 , 1 , 5 , 9
The difference between the terms is 4, so our multiplier is 4 n
4 , 8 , 12 , 16 ( The 4 times tables )
-3 , 1 , 5 , 9 ( The original sequence )
What are we doing to get from the 4 times tables to get to the original sequence?
4 - - 3 = 7
8 - 1 = 7
12 - 5 = 7
16 - 9 = 7
We are subtracting 7 so our complete general term is 4 n -7
