Sumit Gupta  (11 years ago)

1+2-0=3
2+3+1=6
3+6+-2=7
6+7+1=14
7+14-4=17
14+17+1=32

Successive numbers in the series are added.
Then we divide the process into two processes.
These two processes are used alternatively.
First Process: subtract i (where i = 0,2,4,6..)
Second Process: Add 1

Thus 17 is the missing number
