• let numbr be x
  (17-x)/(17-x)=(34-x)/(42-x)
  
  (17-x)(42-x)=( 34-x )(17-x)
  
  714 -578 =42x -34x
  x= 17

• numbers must be 14, 17, 34, & 42
  The solution is "2". If you subtract 2 from 14 and 17, you get 12 and 15. If you subtract 2 from 34 and 42, you arrive at 32 and 40. The ratios 12:15 and 32:40 both simplify to 4:5 (or 4/5 or .8).

• (14-x)/(17-x)=(34-x)/(42-x)
  (14-x)(42-x)=(34-x)(17-x)
  588-14x-42x+x2=578-34x-17x+x2
  10=5x
  x=10/5
  x=2
