The set starts with 1 and ends at 41. So it's finite because it has a fixed number of elements and it doesn't go on forever.

{1, 9, 17, . . ., 41} this is a finite set (as you can see, nothing is coming after 41

in case you have {1, 9, 17, . . ., 41,......} means you have something after 41 and we do not see end; so, in this case the set would be an infinite set
