Consider the first four terms of the sequence below. -3, -12, -48, -192, . . . What is the 8th term of this sequence? A. -49,152
1 answer:
Answer:
A
Step-by-step explanation:
there is a common ratio between consecutive terms , that is
- 12 ÷ - 3 = - 48 ÷ - 12 = - 192 ÷ - 48 = 4
this indicates the sequence is geometric with nth term
= a₁
where a₁ is the first term and r the common ratio
here a₁ = - 3 and r = 4 , then
a₈ = - 3 × = - 3 × 16,384 = - 49,152

set up as a system of equations. for them to cancle out make the y of one equation negative. I'll be making the second one negative ( it doesn't matter though)
it will look like:
make the two equations on top of eachother and line the terms up. Then combine them. The variable "y" will cancle out and you'll be left with
then you will add 3x to both sides to get then divide both sides by 3 to get
if you plug in 5 for x into both of the original equations you will see that they will both make $100 in five hours. So you answer is 5
