Answer:
Y= -4 :)

Steps:
Apply rule
-y + 3 = 7
Subtract 3 from both sides
-y + 3 - 3 = 7 - 3
Simplify
-y = 4
Divide both sides by -1
-y/-1 = 4/-1
Simplify
y = -4

Choose the explicit and recursive formulas for the geometric sequence 45, 135, 405, 1215, 3645, .... PLEASE HELP ASAP

sesenic [268]

Answer:

Option (B)

Step-by-step explanation:

Given sequence is 45, 135, 405, 1215, 3645..........

Since it's a geometric sequence,

Common ratio of each successive term to the previous term

r = $\frac{135}{45}=3$

First term of the sequence 'a' = 45

Explicit formula of a geometric sequence will be,

$a_n=a(r)^{n-1}$

$a_n=45(3)^{n-1}$

Recursive formula of this sequence will be,

$a_n=3(a_{n-1})$ , $a_1=45$

Therefore, Option (B) will be the answer.
