Hi, im trying to write a matlab program for a recursive sequence. I worked out the sequence right i think but cant get the figures right in the program. Heres the program I have so far:

%recursive program for water
%dam cycling down to empty

clear
format long
A=32;
fprintf(' Week Megalitres\n\n');

for n=1:10;
A=A+9-3*n;

disp([n A])
end

These are what i get-

Week Megalitres

1 38

2 41

3 41

4 38

5 32

6 23

7 11

8 -4

9 -22

10 -43

But these are the figures i require-

1 38

2 42

3 44

4 44

5 42

6 38

7 32

8 24

9 14

10 2

The problem is where i have 3*n it should be be going up by 2(n+1) at a time. ie 3,5,7,9 whereas mine is going up as 3,6,9,12.

Can anybody see where ive got it wrong?
Thankyou

I'm not used to Matlab, but I think you need to do the following:
clear
format long
A=38;
fprintf(' Week Megalitres\n\n');

for n=1:10;
disp([n A])
A=A-(2*(n-4))

end
