Answer:
2/5
Step-by-step explanation:
Answer: 20
Step-by-step explanation:
You find the mean by adding up all the numbers in a data set, then dividing by the number added.
18 + 15 + 22 + 18 + 25 + 19 + 23 + 20 = 160
We added 8 numbers together, so we divide 160 by 8
160/8 = 20
10, 5, 20, 10, 40, 20, 80, 40, 160, 80,
Next Three Numbers: 20, 80, 40
Pattern: Take half of the first term. 1/2 of 10 = 5 which is the second term.
Next, multiply the second term by 4. 5 times 4 = 20
Divide 20 by 4 to get 10
Multiply 10 by 4 to get 40
---------------
Take half of 40 to get 20 (the first of the three missing terms)
Multiply 20 by 4 to get 80 (the second missing term)
Multiply 80 by 1/2 to get 40 (the third missing term)
