You can put this solution on YOUR website! The sequence 3,9,27,81,243.... can be rewritten as:
3^1, 3^2, 3^3, 3^4, 3^5........
So the first term is: 3^1
Second term: 3^2 or (3*3)
Third term: 3^3 or (3*3*3)
Continue this pattern and the 100th term is: 3^100
and the nth term is: 3^n
There is no acutal number for 3^n because you don't know what n equals. The actual number for 3^100 = 5.15377521 × 10^47. This is a huge number which is why I didn't write it out and just left it as 3^100.
