It is a geometric seies...

3 6 12 24 48 96 192 384 768 1536 3072

To find any term of a geometric sequence:

where a1 is the first term of the sequence, r is the common ratio, n is the number of the term to find.

here a1 = 3  and common ratio is 2   and we have to find 11th term so...n equals 11

a11 =  3 x 2^(11-1)

      = 3 x 2^10

       = 3 x 1024

Answer       =  3072
