Questions 1, 2, and 5 are correct.
Question 3:
To find the common difference, we can subtract the last two numbers.
60 - 47 = 13
So, the common difference is 13
We can add 13 to each term to get the next term.
8 + 13 = 21
21 + 13 = 34
So, 8, 21, 34, 47, 60
Question 4:
To find the common difference, we can subtract the last two numbers.
8/3 - 2 = 2/3
So, the common difference is 2/3
We can add 2/3 to each term to get the next term.
0 + 2/3 = 2/3
2/3 + 2/3 = 4/3
So, 0, 2/3, 4/3, 2, 8/3
Question 4:
Since we are only given the first and last number, we need to find a number we can subtract that we get -13 at the end. The distance between 3 and -13 is 16. We can divide this by 4 since there are 4 numbers before -13.
16 / 4 = 4
Since the number is going down, the common difference is going to be -4.
Subtract find the next terms.
3 - 4 = -1
-1 - 4 = -5
-5 - 4 = -9
-9 - 4 = -13
So, 3, -1, -5, -9, -13
Best of Luck!
