Answer:
1 
Step-by-step explanation:
Note there is a common ratio between consecutive terms, that is
10 ÷ 20 = 5 ÷ 10 = 2 
÷ 5 =
Thus to obtain the next term in the sequence multiply the previous term by

Step-by-step explanation:
Answer: -2x+7y+16
Step-by-step explanation:
1. Distribute 2 through the parentheses
- 4x+6y+3(5-2x)+1+y
- 4x+6y+15-6x+1+y
2. Collect like terms
- -2x+6y+15+1+y
- -2x+7y+15+1
- -2x+7y+16
3. Solution, -2x+7y+16
U=4 because 3 x 4 is equal to 12
So I think that number 6 is just dividing by 3 and the second one doesn't like divide so number 7 is no and number 6 is yes
