The sum of three consecutive odd numbers is 38 more than the average of these numbers. what is the first of these numbers ?
Let the numbers be `x , x + 2 and x + 4`
Then `(x + x + 2 + x + 4) - ((x + x + 2 + x + 4))/(3)` = 38
or `(3x + 6) - ((3x + 6))/(3)` = 38 or `2(3x + 6)` = 114 or `6x = 102 or x = 17`
So, first number = `x = 17.`
