Answer:
Option D is correct that is 6 is 2nd term of the sequence.
Step-by-step explanation:
We are given with a formula which generates the terms of a sequence,
[tex]a_n=3\times n[/tex]
we have to find 2nd term,
For the second term we put value of n = 2
Thus,
[tex]a_2=3\times2[/tex]
[tex]a_2=6[/tex]
Therefore, Option D is correct that is 6 is 2nd term of the sequence.
