[NTG-context] Create the values of a sequence with Lua

Hi,
The idea is to fill the array with the sequence defined by
p(0) = 0.3 and p(n + 1) = 0.3 + 0.7*p(n)
The problem is that I don't really master Lua but I will learn when I have
some time!
Thanks for your help.

\starttext
\startluacode
context.startxtable({"align={middle,lohi},width=2cm,bodyfont=9pt"})
p = {}
p[0] = 0.3
for i=0,19 do
p[i+1] = 0.3+0.7*p[i]^2 end
context.startxrow()
for i=0,19 do
context.startxcell() context(i) context.stopxcell()
context.startxcell() context(i+1) context.stopxcell()
context.startxcell() context("%0.8f",p[i] ) context.stopxcell()
context.stopxrow()
end
context.stopxtable()
\stopluacode
\stoptext
