Three consecutive even numbers have a sum where one half of that sum is between 90 and 105. write an inequality to find the the three numbers. let n represents the smallest even number. solve the inequality

90 <  [( n + n + 2 + n + 4) / 2] < 105

90 <  (3n + 6) / 2 < 105

3n + 6 > 180      and       3n + 6 <  210

n > 58     ,     n <  68

58  < n < 68   answer

c-   36
