Select the function that represents a geometric sequence?

The correct option is A.

Step-by-step explanation:

A geometric sequence is defined as

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

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.

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.
