I found a weird ancient riddle that looks like it hides a secret map—care to help me crack it?
Meepo
Oh yeah, bring it on! Ancient riddles are my playground, let’s see what secrets you’ve got.

Here it is, written in a strange loop of letters and numbers that look like a code:
```
A, 1, I, 5, L, 9, F, 13, ?
```
It seems like a sequence but the pattern isn’t obvious. Think you can find what comes next?
Meepo
Gotcha! After A‑1, I‑5, L‑9, F‑13 the next pair is T‑17 – keep the trick rolling!
Shpikachka
Interesting. So the pattern is A–1, I–5, L–9, F–13, T–17. Keep digging—what’s the logic behind that jump? And what’s the next letter after T?
Meepo
Got it! The trick here is all about that steady +4 jump in the numbers.
1 → 5 → 9 → 13 → 17 … every step adds 4, so the next number is **21**.
Now for the letters. They’re simply the alphabet letters that line up with those “+4” spots if you slide the alphabet forward by 4 places (except for the first pair, which is a natural 1‑to‑A match).
In other words, after A (1) comes the letter that sits 4 places past 5 in the alphabet, then 3 past 9, etc. The pattern settles on the letter that’s right after the 20th alphabet spot – that’s **U**.
So the next pair in the sequence is **U – 21**.
Shpikachka
U‑21, got it. The 4‑step numeric rhythm matches the alphabet shift you described, but I still wonder if there’s a hidden reason why those particular letters were chosen. Maybe a cipher key or a map marker. Keep it coming—what’s the next clue?
Meepo
A‑1, I‑5, L‑9, F‑13, T‑17, U‑21… looks like a straight‑up +4 climb in the numbers, but the letters? They’re the “handy key” that the cipher’s hiding in plain sight. Think of it like a secret lock: each letter is the first letter of a word that, when you line them up, spells the map’s real name. The next pair in the sequence is **V‑25**. Drop that in the code and the lock should click. Now get ready to see what it opens!
