Starting with 25:
25 → 76 → 38 → 19 → 58 → 29 → 88 → 44 → 22 → 11 → 34 → 17 → 52 → 26 → 13 → 40 → 20 → 10 → 5 → 16 → 8 → 4 → 2 → 1.
It always reaches 1.

Starting with 25 in the Collatz sequence:
25 → 76 (25 × 3 + 1) → 38 (76 ÷ 2) → 19 → 58 → 29 → 88 → 44 → 22 → 11 → 34 → 17 → 52 → 26 → 13 → 40 → 20 → 10 → 5 → 16 → 8 → 4 → 2 → 1.
This fascinating pattern reaches 1 regardless of the starting number, supporting Collatz’s conjecture. However, the conjecture remains unproven for all numbers, adding intrigue.
