The sequence an = 1(3)^(n − 1) is graphed below: find the average rate of change between n = 1 and n = 3. a)1/3 b) 1 c) 3 d) 4

The correct option is D. The average rate of change between n = 1 and n = 3 is 4.

Step-by-step explanation:

The given sequence is defined as

The average rate of change from x₁ and x₂ is

At x=1,

At x=3,

The average rate of change between n = 1 and n = 3.

The average rate of change between n = 1 and n = 3 is 4. Therefore option D is correct.

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
