## Repetition (for Statement)...

```a=100
b=10

1)c=a-b
2)d=c*2-k2; k2=(b*2)
3)e=d*2-k3;k3=k2*2
4)f=e*2-k4;k4=k3*2
30) (...)
z=c+d+e+f+(...)
z=?
```

I need a for Statement that calculates this mathematical sequence.

## For loop and non local index...

Hello,

I have a little question about the property "local" or not of a index in a for loop.

I notice that when I make "for loop" the index i is not local. In the small example, when I ask to evaluate i after having done this loop, the answer is 5 and not i.

Example :

for i from 1 to 4 do
i^2
od;

i; --> 5

How can I do to ask Maple to use index as local ?

Thanks a lot for your help.
