Answer:
4
Step-by-step explanation:
x butterflies and y dragonflies
4 < x + y 《 8
x = 2y
4 < 2y + y < 8
4 < 3y < 8
Only multiple of 2 between 4 and 8 is 6
So 3y = 6
y = 2
x = 2y = 4

= 7.
Ratio means multiply/divide.
To get the next number, multiply number by common ratio.
To get a previous number, divide by common ratio.
Since we want the next number...
2nd term: 7 x -2 = -14
3rd term: -14 x -2 = 28
4th term: 28 x -2 = -56
5th term: -56 x -2 = 112
Keep going until 9th term!
Answer:
Your answer should be -8.
