The one closest to the Middle if your sequence is of an even set of digits. The median will be a specific number if you have a sequence of odd digits.

On the back of the card, the last 3 digits on the signature bar
The question does not contain a sequence but a single large number whose digits are the digits of the sequence, 3n run together. There is only one number, not a sequence, so there is no nth term.
It depends on the credit card. Visa and Mastercard both have 16 digits. American Express has 15.
if repeating is allowed... 36 (6x6, for the last two digits) If not, 6 (3x2, last two digits)
Probably not. Some of the digits are probably check digits, calculated from the other digits, based on some formula. This means that if any one of the digits changes, another digits - or other digits - have to change, too.
