What is the greatest of 3 consecutive integers whose sum is 18 ? Choices.
A) 6
B) 7
C) 8
D) 9
E) 5
The sum of three consecutive integers can be written as n + (n + 1) + (n + 2) = 3n + 3   If the sum is 24, we need to solve the equation 3n + 3 + (  + 1) + (  + 2)=

3n + 3   If the sum is 24, we need to solve the equation 3n + 3= 18;   =&gt; 3n = 15;   =&gt; n = 5   The greatest of the three numbers is therefore   5 + 2=
