Question 979757
40 consecutive numbers add up to 100.  
The numbers have to start less than 1.  The average is 2.5, so that is the middle of 40 integers.
sum from -1 to -17 is -{n*(n+1)/2}=-153
numbers 0,1,2 add up to 3.
Integers greater than 2 add up to 250.
Another way of saying that is that we want consecutive numbers from 1 that add up to 253,

n*(n+1)/2=253;  n(n+1)=512
n^2+n-506=0; (n+23)(n-22)=0; n=22, -23, positive root only.

The number at the top are 22
The number at the bottom is -17.
Zero is the 40th number.
The consecutive integers (40) are from -17 to 22.

ANSWER: minus 17 is the smallest.
