If n is an odd interger which equation can be used to find 3 consecutive odd interfere whose sum is -3

I did not copy, my work

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

numbers are -3,-1,1
