1. Since the numbers are consecutive, LEt them be x,y and z
   So,
   x-y = -1
   y-z = -1
   x-y-z = -13
   On solving these, we get x = 10 , y = 11 , z = 12

2. let the 3 consecutive odd numbers are;2x+1,2x+3,2x+5
   given condition is sumof last to odd numbers is 13 more.
   so 2x+1+2x+3=2x+5+13
   2x=14
   x=7
   so the numbers are:-15,17,19
