As we learnt

General term of the sequence

The nth term of sequence denoted by Tn.

 

We can check the options in this question as identifying a pattern directly is difficult

For Option C

 T_n=2\times 3^{n-1}

For n=1; T_1=2

For n=2; T_2=6

For n = 3, T3 = 18

and so on.

So, this option is correct
