You can put this solution on YOUR website!
Arithmetic means each term changes based on adding or subtracting.
Geometric means each term changes based on multiplication (or division).
1. You are adding 6 to get to each successive term.
2. You are multiplying by 3/2 to get each successive term.
3. You are adding 10 to get to each successive term.
4. You are multiplying by four to get each successive term.
5. You are subtracting 2 to get each successive term.
6. You are multiplying by 3/4 to get each successive term.
Apply the rule I established above and this problem is finished!
