Question

Find the 10th term of the geometric sequence 1, 3, 9, .

Answer 1

Answer:

19683

Step-by-step explanation:

As the formula of the geometric sequence:

$a_{n} =a_{1} *r^{n-1}$

In the sequence of 1, 3, 9..., you have a1 = 1 and r = 3. Therefore:

$a_{10} =1 *3^{10-1} = 3^{9} =19683$

Hope this helps!
