Question

Select the function that represents a geometric sequence. A. A(n) = P + (n-1)• P, where nis a positive integer B. A(n) = 1 + (1 - 1). P, where n is a positive integer C. A(n) = (n-1)(P. n)' where nis any real number D. A(n) = P(1 + )" - 1, where n is a positive integer

Answer 1

We know that the geometric seria has the form:

`A(n)=a(r)^n`

SO the geometric serie is the number D because is the only one hat has an exponent
