use variable to set the range of a for loop

Hi;
For sure there's an easy answer to this one that I am not finding..

I first set a variable, say

b1a:] max=5

then I want to use max to set the range for a for loop like so (it should run for i in 1:5)

b1a:] for i in {1..$max}; do echo $i; done
{1..5}

I would like the output to match this:

b1a:] for i in {1..5}; do echo $i; done
1
2
3
4
5

Any ideas?

Thanks!
