Answer:
a(4) = 15/4
Step-by-step explanation:
The general formula for a geometric series with common ratio r and first term a(1) is
a(n) = a(1)*r^(n - 1)
and so, if a(1) = 30 and r = 1/2, we have
a(n) = 30*(1/2)^(n - 1)
and the fourth term is then:
a(4) = 30*(1/2)^(4 - 1) = 30/8 = 15/4
Answer:
g(x) = x+5
Step-by-step explanation:
Given that,


We need to find the polynomial. We know that, Euclid division lemma states that

Where
f(x) is dividend
g(x) is the poynomial
q(x) is quotient
r(x) is remainder
So,

So, the polynomial is (x+5).
