Question 439352
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
