Wouldn't you just work your way out from the inside.
3100=97
2(97)=99
199=98

lets start from inside,,
............(95  (96  (97  ( 98  ( 99 100) ) ) ) ) )
............(95  (96 (97  (98  99 + 100 ) ....
..........(95  (96  (97  98 + 99  100 )..
.........(95  96 + 97  98 + 99  100)
sign alternates everytime for each no..i.e. 2 consecutive nos. have opposite signs..
in the end, we shall have
1 2 +3  4 ......... 100
(1+3+5......99)  (2 +4 +6 ...100)
25(100  102)
=50
was that corretc ?
