Answer:
1. 5, 10, 15, 20, = C. Arithmetic, common difference is 5
2. 128, 32, 8, 2, = Geometric , Common ratio is 0.25
3. 20, 17, 14, 11, = Arithmetic , Common difference is -3
4. 1, 3, 9, 27, = Geometric , common ratio is 3
Step-by-step explanation:
In arithmetic sequence we calculate the common difference and it is gotten by:
In geometric progression we calculate common ratio and it is gotten by :

Step-by-step explanation:
Take one polynomial from the other means to perform the sub.traction of them. Recall that it is better to use grouping symbols when subtracting polynomials, so we get the signs right when combining like terms:
The indicated subtraction is:
Make sure that before removing the grouping symbol (parenthesis) that is preceded by a negative sign, we change the signs of every term inside it. Then combine like terms to get the final answer:
