Answer:
Option d is correct.
Step-by-step explanation:
We have given a formula 
We will put different values of n so, as to get 
from the given formula
When n =1 we get
When n=2 we get
When n=3 we get
We can see that next term is 3 more than the previous term
Hence, 
Therefore, Option d is correct.
Answer: 5x2-2x-7
Step-by-step explanation:
(4x2 + 3x - 1) + (x2 - 5x - 6)
=4x2+3x-1+x2-5x-6
=5x2-2x-7
Answer:
-162
Step-by-step explanation:
Answer: no
Step-by-step explanation:
To be a linear equation, the equation must be written in y = mx + b. When an equation is squared, it is a parabola. Linear functions are straight lines.
Let a₁ = the first term.
Because each previous term is 1/5 of the value of the current term, the geometric sequence is
a₁, 5a₁, 25a₁, ...,
The common ratio is r = 5.
The n-th term is
The fifth term is 781.25. Therefore
a₁*5⁴ = 781.25
625a₁ = 781.25
a₁ = 1.25
