Start At One And Add One Forever
POW: 04-20-2026
Riddle: Start at one and add one forever; I grow but never end. What am I?
Answer: Infinity.
It’s the process of counting: start at 1, then keep adding 1—2, 3, 4, and so on—without stopping.
The total “grows” because the number increases, but it “never ends” because there’s no largest number; you can always add one more.
Infinity is not a specific number, but rather a concept representing something without any bound or end, perfectly matching the description in the riddle.
