Answer:
Option B
Step-by-step explanation:
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.
