Which of the following is not an arithmetic sequence?
4,7,10,13,16
15,9,3,-3,-9
1,2,3,4,5
2,4,8,16,32

2,4,8,16,32

Step-by-step explanation:

In an arithmetic sequence, consecutive terms differ by a constant value which is called the common difference.

Looking at the given sequences,

1) 4,7,10,13,16

7 - 4 = 10 - 7 = 13 - 10 = 3

The common difference is 3. Therefore, it is an arithmetic sequence.

2) 15,9,3,-3,-9

9 - 15 = 3 - 9 = - 3 - 3 = - 6

The common difference is - 6. Therefore, it is an arithmetic sequence.

3) 1,2,3,4,5

2 - 1 = 3 - 2 = 4 - 3 = 5 - 4 = 1

The common difference is 1. Therefore, it is an arithmetic sequence.

4) 2,4,8,16,32

4 - 2 is not equal to 8 - 4

Therefore, it is not an arithmetic sequence.

Step-by-step explanation:

2,4,8,16,32

Difference is not common

4-2 = 2

8-4 = 4

This is a geometric sequence

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
