Question

Study the graphs of the infinite sequences below. Answer questions 4 through 11 by circling the letters of all graphs, if any, for which the statement is true. There can be more than one answer! (This question has been answered a couple of times on chegg but they are all answered differently which scares me so could you please verify and make sure that your answers are correct, thank you!)

4. The sequence is arithmetic. 5. The sequence is geometric. 6. The sequence is the Fibonacci sequence. A BCD A B CD A BCD The sequence sums to a finite number. 8. The domain of the sequence is the set of A BCD non-negative integers. 9. Sequence(s) where one quantity changes at a A BCD constant rate per interval relative to another quantity. 10. Sequence(s) where one quantity changes at a constant percentage rate per interval relative to another quantity 11. One possible definition of the sequence is: A BCD a" = a"-' + (n-2); ais|

Explanation / Answer

4. option (A)

because the common difference between any two numbers is same

5. option (B)

Here we can see clearly the difference is clearly increaing in the output.

6. option (D)

every number is the addition of previous two numbeers

7.option (C)

the given graph is an exponentially decaying function.

Hence the sequence will become some finite number

8.option (A)

per interval change means nothing arithmetic sequence.

common differnce is same per interval

9 option (B)

percentage interval same means the common ratio is same.

HEnce geometric sequence.

hence option B

11.option (D)

take n=3

a3= a2 + n2 = 2+2=4=a3

the given sequence is a fibinocci series..
