# A Single Letter is missing from each, can you figure it out to find the answer and the question?

Grasshopper, in order to know the answer you must first figure out the question.

H, H, D, P, ?                     (2)
P, L, T, Q, P, H, H, ?            (5)
R, C, C, U, B, A, ?               (9)
A, K, Q, J, T, N, E, ?           (11)
M, V, E, M, J, S, ?              (14)
D, P, N, G, C, M, ?              (15)
M, K, S, P, S, ?                 (16)
Y, C, A, G, ?                    (18)
A, T, G, C, L, V, ?              (48)

H, H, L, B, B, C, ?             (613)
A, A, N, S, A, ?             (371017)


Hint 1:

The answer is 3 letters long

Hint 2 (Bounty Hint):

H, H, D, P, ?, Z.                     (2)
M, K, S, PH, S, ?, DP, DD, DQ...     (16)

• Something simple like "Discover the missing letters" would probably suffice. is there supposed to be a letter missing from the fourth line? - looks like you already fixed that. :) – Bailey M Jul 24 '15 at 20:02
• @BaileyM It isn't just about discovering the letters, the numbers are also involved – qwertylpc Jul 24 '15 at 20:03
• Is the question made from discovering the missing letters? – Doge Jul 24 '15 at 20:27
• Grasshopper, eh? – AJL Jul 25 '15 at 1:18
• @qwertylpc Well, you've inspired another puzzle from me: puzzling.stackexchange.com/questions/18363/… – VictorHenry Jul 26 '15 at 0:59

Alright, I'm going to start a partial answer, we'll see if it goes anywhere.

Missing letters:

Edit: Thanks to minitech for number 6! Thanks to Len for number 1! Thanks to Geobits for number 7!

1. H (Hestia, Hades, Demeter, Poseidon, Hera) - Cronus and Rhea's Children
2. O (Point, Line, Triangle, ..., Heptagon, Octagon) - Polygon by number of sides
3. I (Russia, Canada, China, United States, Brazil, Australia, India) - Countries by Area
4. S (Ace, King, Queen, Jack, ..., Eight, Seven) - Cards
5. U (Mercury, Venus, Earth, ..., Saturn, Uranus) - Planets
6. M (Delaware, Pennsylvania, New Jersey, ..., Massachusetts, Maryland) - US States by Ratification Date
7. B (McDonalds, KFC, Subway, Pizza Hut, Starbucks, Burger King) - Largest Fast Food Chains in the World by number of stores
8. R (Yankees, Cardinals, Athletics, Giants, Red Sox) - Most World Series titles
9. L (Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra) - Signs of the zodiac
10. T (Zero, One, Two, Three, ..., Nine, Ten) - Counting to ten
11. N (Hydrogen, Helium, Lithium, ..., Carbon, Nitrogen) - Periodic Table Elements
12. E (Asia, Africa, North America, South America, Antarctica, Europe) - Continents by Area

Cleaning up the list and adding the numbers gives us:

H 2
O 5
I 9
S 11
U 14
M 15
B 16
R 18
L 48
T 112
N 613
E 371017

"Deciphered the numbers based off VictorHenry's answer! All I had to do was... add a couple suggestive spaces:"

H 2
O 5
I 9
S 11
U 14
M 15
B 16
R 18
L 4 8
T 1 12
N 6 13
E 3 7 10 17

Each set of numbers tells us where that letter is located in the final phrase:
1 2 3 4 5 6 7 8 9101112 131415161718
T H E L O N E L I E S T N U M B E R
So the final answer is ONE!

• #7 is B or BK, at least according to this list. I see them in different orders on a couple other sites, but they may be measuring differently. I only add the BK option because the hint has some with double letters, but I assume it's just B. – Set Big O Jul 27 '15 at 16:03
• I don't know what the numbers are, but the letters anagram to OH NUMBER LIST, or something along those lines. – Set Big O Jul 27 '15 at 16:16
• @Geobits it could also be HI LOST NUMBER – tfitzger Jul 27 '15 at 21:31

Deciphered the numbers based off VictorHenry's answer! All I had to do was...

H [2]
O [5]
I [9]
S [11]
U [14]
M [15]
B [16]
R [18]
L [4 8]
T [1 12]
N [6 13]
E [3 7 10 17]
Each set of numbers tells us where that letter is located in the final phrase. It spells out THE LONELIEST NUMBER, so the final answer is ONE!

• Nicely done! I was going nowhere with those numbers, but I knew someone would solve it! – VictorHenry Jul 28 '15 at 14:29
• @VictorHenry and Deusovi Seeing as you both contributed a lot, I am not sure I know how to best award the bounty and the correct answer. I have posted about it on Puzzling Meta here: meta.puzzling.stackexchange.com/questions/3209/…, if either of you guys have ideas please let me know – qwertylpc Jul 28 '15 at 14:38
• @qwertylpc Well in this particular case, several of my answers were crowdsourced, and I feel like Deusovi made the major leap, at least as far as the "lateral thinking" part of the puzzle went. Makes sense to me to give it to Deusovi. – VictorHenry Jul 28 '15 at 14:57
• @JamieBarker You do know that serial upvoting is not allowed on SE and can get you into trouble? – mmking Jul 29 '15 at 14:31
• @JamieBarker You mean 2 or more people? No. It is considered serial upvoting if you go around and upvote one person several times in a short period of time. And by "a couple of upvotes", I'm assuming you mean more than one or two. Do read the meta post I linked to. – mmking Jul 29 '15 at 14:47
