Question 1089088
find all three sets of consecutive integers whose sum is less than 24
????????????
if the sum of the least and twice the next greater integer is twice the greatest integer 
n + 2(n+1) = 2(n+2)
n + 2n + 2 = 2n + 4
n + 2n - 2n = 4 - 2
n = 2
then
2, 3, 4 are the three consecutive integers
