n is an interger (if you want to make it more complecated, do 2n+1 is an odd number where n=a whole number )
all consecutive odd integers are 2 away from each other numbers are n,n+2,n+4 their sum is -3 n+n+2+n+4=-3 add like terms 3n+6=-3 subtract 6 3n=-9 divide 3 n=-3 subsitue number are n,n+2,n+4 n+2=-3+2=-1 n+4=-3+4=1
