A1 = 2, n = 10, r = 3, an = ?

Solving for an:
an = a1⚫3^(n - 1)
an = 2 ⚫3^(10 - 1)
an = 2 ⚫3^9
an = 2 ⚫ 19,683
an = 39,366


The tenth term of the geometric sequence is 39,366.

The formula to find the geometric sequence is : 
 
                   a_{n}=a_{1}r^{n-1}
  where : 
                   a_{1}=2, r=3, a_{10}=?
  so,
                   a_{n}=a_{1}r^{n-1}
                   a_{10}=2(3^{10-1})
                   a_{10}=2(3^9)
                   a_{10}=2(19683)
                   a_{10}=39366
 
  Therefore, the 10th term of the sequence is 39366
