0,2,2,3,3,5,8,4,10,(?),5,17

• A. 6
• B. 7
• C. 9
• D. 15

Answer 1

The correct option is D 15

The given series is 0,2,2,3,3,5,8,4,10,(?),5,17
Rationale: The numbers in the series by themselves have no relation to one another.On breaking it into 2 series also there is no fixed patter.Divide the series into 3 subseries i.e.
0,3,8,? ---Series I
2,3,4,5 ---Series II
2,5,10,17--Series III
In Series I the numbers incerment in 3,5,7...
In series II the numbers increment by 1
In series III the numbers increment by 3,5,7,..
Hence the missing number of the series(in series I) is 8+7=15
