Solution
The correct option is C 10
The given sequence is a combination of three series :
I. 1st, 4th, 7th, 10th, 13th term i.e. 2, 4, 6, 8, (....)
II. 2nd, 5th, 8th, 11th term 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 number is 10.
