Answer: A) 9
==========================================================
Explanation:
- x = smallest
- x+2 = middle
- x+4 = largest
I added on 2 each time to get the next term.
We'll add those three expressions.
Then set the sum equal to 33, and solve for x.
x + (x+2) + (x+4) = 33
3x+6 = 33
3x = 33-6
3x = 27
x = 27/3
x = 9 is the answer
--------------
Extra info:
x+2 = 9+2 = 11 is the middle number
x+4 = 9+4 = 13 is the largest
Check:
9+11+13 = 33
The answer is confirmed.
