Identify a1 r and n for the sum of the geometric sequence. 1/2 + 3/8 + 9/32 + 27/128 + 81/512 a1= r= n=

a1=1/2

r=3/4

n=5

Step-by-step explanation:

a1 is the first term in the geometric series

a1=1/2  

r is the common ratio of the first and second term

r=(3/8)/(1/2)

r=3/4

where n is the no of the term in the geometric series

In algebra, the polynomial remainder theorem or little Bézout's theorem is an application of Euclidean division of polynomials. It expresses that the rest of the division of a polynomial by a direct polynomial is equivalent to. Specifically, is a divisor of if and just if a property known as the factor hypothesis.

The number multiplied at each stage of a geometric sequence is called its common ratio.

The next question after that is 1 269/512
