This problem is invalid.
Since the only conditions are that six terms must be positive and odd and have a total of 13 digits, an infinite number of cases are possible.
Here are two options:
11, 13, 15, 17, 19, 101
13, 11, 15, 17, 19, 101
Since the sequence does not have to be ascending, any of the answer choices could be a divisor of the first term.
Ignore this problem.
