Find the 11th term of the geometric sequence 1, 4, 16, ...

1 answer:

6 0

Answer:

a(11) = 4^10 = 1048576

Step-by-step explanation:

The first term of this geometric sequence, a(1), is 1, and the common ratio, r, is 4. Each new term is 4 times the previous term. Thus,

a(n) = 1*4^(n - 1), and

a(11) = 4^10 = 1048576
