Which graph represents a geometric sequence?

Geometric sequence--

The sequence is said to be geometric if each of the term of the sequence is obtained by multiplying the preceding term of the sequence by a fixed constant.

This fixed constant is known as  a common ratio and is denoted by r.

i.e. the sequence is given by:

                 a,ar,ar²,ar³,.....

The graph which represents the geometric sequence is attached to the answer.

Since the table of values are as follows:

          x             y

          1              1

          2             2

          3             4

          4             8

i.e. the sequence 1,2,4,8

form a geometric sequence.

Since the common ratio of the sequence is: 2 with first term as: 1

(first term is: 1

second term is: 1×2=2

Third term is: 2×2=4

and fourth term is: 4×2=8 )

It's B. Second Graph.
