Answer:

Number of players left after 10 rounds = 64

Step-by-step explanation:

This is an example of geometric progression,

First term = 65,536

[tex]\texttt{Common ratio = }\frac{1}{2}[/tex]

Now we need to term of GP when 10 rounds of play is completed, that is eleventh term of GP.

N th term of GP is given by

             [tex]t_n=ar^{n-1}[/tex]

Substituting

               [tex]t_{11}=65536\times \left ( \frac{1}{2}\right )^{11-1}\\\\t_{11}=65536\times \left ( \frac{1}{2}\right )^{10}=64[/tex]

Number of players left after 10 rounds = 64
