# 1+2+3+.............................=?

Srinivasa Ramanujan proof 1+2+3+-----------------=-1/12

my proof 1-2+3-4+5-6…………………………………………

1-(1+3)/2 +3 -(3+5)/2 +5 -(5+7)/2……………………………….

1-1/2-3/2+3-3/2-5/2+5-5/2……………………………………..

=1/2

(1+2+3+4+………………………..=s)-(1-2+3-4+5-6…………………=1/2)

2(2+4+6+………..)=s-1/2

4(1+2+3+………….)=s-1/2

4s=s-1/2

s=-1/6

1+2+3+4+…………..=-1/6
