for a : 420 .. 700 by 5
var x : array 1 .. 3 of int := init (350, 350, 440)
var y : array 1 .. 3 of int := init (130, 180, 130)
drawfillpolygon (x + a, y, 3, 102)
drawpolygon (x + a, y, 3, 103)
delay (50)
drawfillpolygon (x + a, y, 3, 77)

you can't add arrays and integers together. Different types.

1)
code:

use code tags

3) an array of integers is not the same as an integer, only an index of an array of integers can be added to an integer

In your case you had it mostly right but you missed one thing
code:

%you had
drawfillpolygon (x+a...)
%what you need
drawfillpolygon (x(1)+a....)

so what you need to do is add a single element of your array to an integer, not the entire array
