Answer:
The correct answer is :
y = 8(x + 2)^2 + -15

Answer:
n = 8
Step-by-step explanation:
This is a geometric sequence where the sum to n terms is
= 
where a is the first term and r the common ratio
r = 6 ÷ 2 = 18 ÷ 6 = 54 ÷ 18 = 3 and a = 2, thus
= 6560
= 6560 ← cancel the 2
- 1 = 6560 (add 1 to both sides )
= 6561
note that 6561 = 
, hence
= ⇒ n = 8
