FIRSTLY - DO NOT GIVE NEGATIVE POINTS TO PEOPLE WHO ARE TRYING TO HELP YOU!

 

IF YOU THINK THAT THEIR ANSWER IS WRONG AND YOU WANT TO COMMENT THEN DO SO WITH A COMMENT POST.  THAT WAY THEY CAN LEARN TOO!

 

0.5 is being added each time.  So I think that the answer you are after is  

 

$$X_0=0.9,\qquad X_n=X_{n-1}+0.5$$

I think it should be 0.4+(0.5*x) X represents the variable to fill in
