Answer:
what is the problem
Step-by-step explanation:
Answer: 3, 6, 9, 12
Step-by-step explanation:
A geometric progression has a common ratio.
2,6, 18 and 54 has a common ratio of 3. When you multiply the first number by 3, you get the second number and the same thing applies to the third number.
1, 5, 25 and 125 has a common ratio of 5. When you multiply the first number by 5, you get the second number and the same thing applies to the third number.
4, 8, 16 and 32 has a common ratio of 2. When you multiply the first number by 2, you get the second number and the same thing applies to the third number.
3, 6, 9 and 12 is an arithmetic progression as 3 is added to each number
2x+y-3z=12
2x=4z-y
x=2z-y/2
Answer:
D
Step-by-step explanation:
You can set up a porportion of 200/50 then x/5000 so then 200 x 5000= 1,000,000 divided by 200 then it will equal 500 so the answer is 500
