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

Option B

Given are 4 sequences and we have to find which one represents a geometric sequence.

We know that geometric sequence will be of the form

a, ar, ar^2,

On scrutinising the options we get first option does not have the term multiplied by common ratio

OPtion I is incorrect

Option II is a geometric sequence with common ratio (1+i)

Option III is not a geometric sequence since the exponents are all real numbers

Option IV is also incorrect.
