Let the 2nd number be x
ACC to the question
1st number = x-3
and 3rd number = x+9
now, x+x-3+x+9/3= 50
therefore, 3x + 6 =150
3x= 144
therefore x = 144/3
x= 48

Answer:
48
Step-by-step explanation:
let second no.= x
first no.=x-3
third no.=x+9
[x+x+x-3+9]/3=50
x+x+x-3+9 = 150
3x =150-6
3x =144
∴ x = 48 or the second number is 48
