The sum of 7 odd integers is 217, what is the largest of the integers? 217/7=31=The average of the integers The 3 nearest odd numbers under 31 is 25,27,29 The 3 nearest odd numbers over 31 is 33,35,37 The sum of 25,27,29,31,33,35,37 is 217. Now i know that 37 is the largest of the odd integers, this is right too, right?
looks good to me also you could have argued as you did in the previous post by saying the seven numbers were x x+2 x+4 x+6 x+8 x+10 x+12
think your way is more creative though, so stick with it
