Question

Select the function that represents a geometric sequence?

Answer 1

A is correct just took the test

Explanation:

Answer 2

The correct option is A.

Explanation:

A geometric sequence is defined as

`A(n)=ar^(n-1)`

Where, a is the first term of the sequence, r is the common ratio and n is number of term. So, n can not be negative or zero.

In option A, the given sequence is

`A(n)=P(1+i)^(n-1)`

Where, n is positive integers.

Here the first term is P and (1+i) is the common ratio. So, this sequence is geometric sequence.

Therefore the correct option is A.
