What is the nth term of the progression 27, 9, 3,...

Answer 1

The common ratio between consecutive terms is 1/3. Therefore, the nth term of this progression can be written as:

27 * (1/3)^(n-1)

So, for example:
- The 4th term would be 27 * (1/3)^(4-1) = 27 * (1/27) = 1
- The 6th term would be 27 * (1/3)^(6-1) = 27 * (1/243) = 0.111...
