If n is an odd integer, which equation can be used to find three consecutive odd integers whose sum is −3?

 

A) n + (n + 1) + (n + 3) = -3 

 

B) n + (n + 1) + (n + 2) = -3 

 

C) n + (n + 2) + (n + 4) = -3 

 

D) n + (n + 2) + (n + 3) = -3

n= 1st odd integer

 

then n+2  would be the NEXT consecutive odd integer and

        n+4  would be the NEXT one after that

 

so  n   +    n+2   +    n+4   would be the sum of three consecutive integers (even or odd)  if three ODD numbers add to a certain sum(which is odd)  there will not be 3 consecutive even numbers that add to that sum (they would only add to a EVEN number)

 

So the answer would be.........?????     Got it?
