O A. A(n) = P(1 + i)n - 1, where n is a positive integer

O B. A(n) = P+(n-1)i• P, where is any real number

O C. A(n) = P(1 + i)n - 1, where n is an real number

O D. A(n) = P + (n-1)i• P, where n is a positive integer​

Respuesta :

A geometric series is the collection of an unlimited number of terms with a fixed ratio between them. The correct option is A.

What is geometrical series?

A geometric series is the collection of an unlimited number of terms with a fixed ratio between them.

An geometric series is a series where the ratio of any two consecutive term is the same. Therefore, the nth term of a geometric series is given as,

[tex]a_n = a_1 \times r^{(n-1)}\\\\A(n) = P(1+i)^{n-1}[/tex]

Hence, the correct option is A.
