You can put this solution on YOUR website! observe the numbers in each of the following sets. determine the missing number (X) in the last set. it starts out like this..
{29,2,27}, {28, -3, 33), {29,7,22}, {X,3, 39}
WHAT IS X.............
------------------------------
The sum of the numbers in each triple is 58.
So X = 58-(3+39)
X = 58-42
X = 16
