The sum of three consecutive odd numbers is 165.what is the sum of the largest number and twice the smallest number?
Logically, the MIDDLE integer is:
From this, you should be able to find the others and answer the question
OR
Algebraically, let the smallest integer be S
Then middle is: S + 2, and largest = S + 4
The sum-equation: S + S + 2 + S + 4 = 165 ensues.
Solve for S, the smallest, and then add 2 and 4 to get the middle and the largest, respectively.
Answer the question!
That's it...nothing COMPLEX and CONFUSING!
