sorry for previous ans. it will be 62
procedure is as same as it was in my prev. post
add 1 before the ques.
so now it become 1 3 4 8 15 31
now,
1+3=4, 1+3+4=8, 3+4+8=15(exclude 1), 1+3+8+15=31, 1+3+4+8+15+31=62

3+4=7 (3,4)
7+1=8
8+8=16 (3,4,8)
16-1=15
15+15=30 (3,4,8,15)
30+1=31
31+31=62 (3,4,8,15,31)
62-1=61
61+61=122 (3,4,8,15,31,61)
122+1=123
(I guess answer is 61)
