Answer:
Option B
Step-by-step explanation:
A) a1 = 3
a2 = 3×20
an = 3 × 20^(n-1)
B) a1 = 20
a2 = 20×3
an = 20 × 3^(n-1)
C and D are not geometric
Answer:
see below
Step-by-step explanation:
You know the relationship between the explicit rule and the recursive rule for a geometric sequence is ...

The given explicit rule tells you a1 = 20, r = 3, so you know the recursive rule is the one shown below.

2x - 3 = y
-3x + 5 = y
-4/5x -2 =y
1/2x + 9 = y
If you triple the height of a barrel the dimensions will triple i belive.
So decrease is 375-250=75
so convert 75/375 to percent
percent means part out of 100 so
x/100=x%
divide 125/375=0.3333/1
multiply by 100/100=33/100=33%
the answer is 33% or B
6a-(n-1)(3a) is the nth term
Expanding we get 6a-3an+3a=9a-3an=3a(3-n)
SOLUTION: nth term is 3a(3-n)
