hm... we can write the sum of three consecutive integers as n + (n + 1) + (n+2) = 3n + 3 = (the sum) we know that n must be an integer, so 3n + 3 must be divisible by 3

oh

n-1,n,n+1 n-1+n+n+1=3n each term is divisible by 3

s the answer 18?
anonymous
  • anonymous
e.g.,24/3=8 middle term is 8 8-1,8,8+1or 7,8,9 are the required terms

  • anonymous
sum is divisible by 3 for 18 18/3=6 6-1,6,6+1 or 5,6,7

each term means all your choices are divisible by 3

3| 18 =6, hence middle one is 6, so the numbers is 5 , 6 ,7 3|24 = 8, hence middle one is 8 , the numbers is 7,8,9 same as others

18 = 5 + 6 + 7 24 = 7 + 8 + 9 33 = 10 + 11 + 12 36 = 11 + 12 + 13 Are you sure you posted the `options` correctly? :o
