12
Answer: Option
Explanation:

The given sequence is a combination of three series :

I. 1st, 4th, 7th, 10th, 13th terms i.e. 2, 4, 6, 8, ?

II. 2nd, 5th, 8th, 11th terms i.e. 1, 4, 7, 10

III. 3rd, 6th, 9th, 12th terms i.e. 2, 5, 8, 11

Clearly, I consists of consecutive even numbers. So, the missing term is 10.

How can we say that there are three series?

It should be proved, series can be more or less, and different series also exist.

Also, the answer seems to tie with 12. So, the answer should be option D.
