write (s);
end
2)
var s;k;I: integer;
begin
s:=3;
I:=3*s;
for k:=3 to 9 do
s:=s+I;
write (s);
end

Answer 1

//1)
var
  s, k: integer;

begin
  s := 4;
  for k := 1 to 3 do
    s := s + 2 * k;
  write(s);// s = 16
end.
//2
var
  s, k, I: integer;

begin
  s := 3;
  I := 3 * s;
  for k := 3 to 9 do
    s := s + I;
  write(s);// s = 66
end.

Answer 2
