4. The sum of four consecutive integers is 2 . What is the least of these integers?
A -3
B -2
$\mathrm{C}-1$
D 0
E 1
SolUTION
C

The four integers cannot all be non-positive since the total is positive. Also, they cannot all be non-negative since the smallest possible total would then be $0+1+2+3=6$. So, they must have at least one negative integer, and at least one positive integer, and hence will include $-1,0$ and 1 . Since these have a total of 0 , the fourth number must be 2 . Thus the least integer is -1 .
