First, let's list | 3^n mod 5 for small n to see if there's a cycle.
3^1 = 3, so 3 mod 5 is 3.

Let's list the intervals:
A: (-∞, -1) ∪ [2, 3)
B: [-2, 4)
So the union would be the combination of these. Let's see. The B set starts at -2, so the leftmost part of the union should be -2, since B goes down to -2. Then A has up to -1, so from -2 to -1 is covered by B (since B ... | (-∞, 4) | false | 0 | 0 |

B is from -2 to 4, so B includes from -2 to 3 (since A's second interval is 2 to 3) and then 3 to 4.
Let me list out the intervals:

B is [-2, 4). So when we take the union, we need to see how these intervals connect.
Let's list the intervals:

Wait, maybe I should write both intervals with their endpoints.
A is two separate intervals: (-∞, -1) and [2, 3).
