Step-by-step explanation:
we know,

Therefore, nth term of a given gp is
16a
The base of 6 is the same, so add 1/2+1/2 =1
6^1 = 6
the greatest is 10 and the least is one but I don't know for sure but I don't know if that what you looking for
Answer:
The rational zero of the polynomial are
.
Step-by-step explanation:
Given polynomial as :
f(x) = 4 x³ - 8 x² - 19 x - 7
Now the ration zero can be find as
,
where P is the constant term
And Q is the coefficient of the highest polynomial
So, From given polynomial , P = -7 , Q = 4
Now , 
I.e
=
Or, The rational zero are 
Hence The rational zero of the polynomial are
. Answer
