Just substitute the number 5 into n since the question is asking for 5th term.

to the both n's

anonymous · Answer

No, just the n which is in the form of power. (n-1)

anonymous · Answer

is it 972?

anonymous · Answer

No, the answer is 324. 
4(3)*n-1 is the question right.
Substitute 5 into n.
4(3)*5-1=4(3)*4
             =4x(3*4)
             =4x81
              =324
