Find the 8th term of the series 1, 3, 9, ...

2187
6561
729
243

Explanation

This is a geometric progression (GP) where each term is multiplied by 3:

1, 3, 9, 27, 81, 243, 729, 2187

Formula:

a_{n} = a \times r^^{(n - 1)}

Here:

a = 1
r = 3
n = 8

So:

a_{8} = 1 \times 3^^{7} = 2187

8th term = 2187
