Since the sequence is geometric, there is some constant
such that the sequence is recursively given by
By this definition, you can recursively substitute into the right hand side the definition for
to find an explicit formula for the
th term.
You know the second term, which means you can find
:
So, the 7th term of the sequence is
Answer: c
Step-by-step explanation:
To solve we have to write 12x as 2x+10x
<span><span>x2</span>+2x+10x+20</span>
taking x and 10 as a common
x(x+2)+10(x+2)
now (x+2) is common
<span>(x+2)(x+10) answer</span>
Answer:
c or 3rd one
