Question 
2, 15, 4, 12, 6, 7, ?, ?
Let the missing terms of the series be x_{1} and x_{2}.
Thus, the sequence 2, 15, 4, 12, 6, 7, x_{1} x_{2} is a combination of two series :
I. 2, 4, 6, x_{1} and II. 15, 12, 7, x_{2}
I consists of consecutive even numbers.
So, missing term, x_{1} = 8.
The pattern in II is  3,  5,......So, missing term, x_{2} = 7  7 = 0.
