Ok Reimy the question came with the ans x=3 then y=2.2, i made t he mistake and put it to two decimal places not realising tehy sequence is one, i will try to be more careful in the future.
How did you come up with 20.25 to divide by 20?

Please don't start a new posting for each reply, stay in the same thread.
This saves me the time to go back and find the posting which deals with the above.
I think our equation was y = 20/x^2 and you wanted y when x = 4.5
what is (4.5)^2 ??
then what is 20/(4.5)^2 ??
