Option B:
The 12th term is 354294.
Solution:
Given data:
and
To find
The given sequence is a geometric sequence.
The general term of the geometric sequence is .
If we have 2 terms of a geometric sequence and
(n > K),
then we can write the general term as .
Here we have and
.
So, n = 7 and k = 4 ( 7 > 4)
This can be written as
Taking cube root on both sides of the equation, we get
r = 3
Hence the 12th term of the geometric sequence is 354294.
