The first term of the series is 3.

The sequence of the condition is:

To get the next term, multiply 3.

This means there is a Common ratio.

This is a Geometric sequence.

After 7 rounds, the total number of people are,


\begin{gathered} a_n=ar^(n-1) \\ a_7=ar^(7-1) \\ a_7=ar^6 \\ a_7=3(3)^6 \\ a_7=3*729 \\ a_7=2187 \end{gathered}
