Find the next three terms of the arithmetic sequence. Then, give the common difference, and write a rule to describe the sequence. 1. 66, 77, 88, 99, . . . (0 points) Tell whether each sequence is arithmetic , geometric , or neither . Then find the next three terms. For each arithmetic or geometric sequence, give the common difference or ratio, and write a rule to describe the sequence. 2. 9, 3, 1, onethird_large, . . . (0 points) 3. 1, 4, 9, 16, . . . (0 points)
help plz :)
first question = you can use the formula \[a_{n}=a_{1}+(n-1).r\] where \[a_{n}\] is the number you want to find ; \[a_{1}\] is the first number in the sequence and r is the common difference.
im confused what goes to each question?
lol, i do connections academys to and it really blows.
