Help me complete these two series : fun brain picking !

Okay, not much more at stake for me than fun here, but can you help me ASAP with those two ?

1/ Which number completes the sequence, and why ?

298 209 129 58 -4

Is it
a/ -13
b/ -93
c/ -66
d/ -57

?

2/ Which letter completes that series, and why ?

C A R R
Is it
a/ S
b/ X
c/ I
d/ Y

?
Thanks for your brain time ! ;-)

298 - 209 = 89
209 - 129 = 80
129 - 58 = 71
54 - -4 = 62
............ 53

I would say:
C A R R Y

1) should be (d)
  298 - 89 = 209
  209 - (89-9) = 129
  129 - (80-9) = 58
   58 - ( 71-9) = -4
    -4 - (62-9) = -57

sirbountyCommented:
I would probably agree that the 2nd one is (d)

Thank, great help on the first one,
still I'm not sure how to justify the answer to the other, except to form a word in English however the contest is in French ;-)
Can't see a logic in their position in the alphabet..why those two R?...

sirbountyCommented:
Hmm - I don't know much French...hard to say on that one... : \

DenisvtAuthor Commented:
Actually don't worry it's a universal logic so nothing to do with the French language, it's just that my guess is the goal is more likely to find the logic between the series of letters than ending up with a word in any language ?

sirbountyCommented:
Then my other 'guess' (purely what it is) would be the position in the alphabet (but that would constitute the English alphabet, wouldn't it?)
Anyway:

C=3  A=1  R=18  R=18 X=24

Only for the reason...
24 is a product of 8 and 3 (and 1 if you want to toss that in there)...

S is 19, I is 9 and of course Y is 25

At least thats the only other pattern I could find...

DenisvtAuthor Commented:
I am also searching around the position in the western alphabet, as I guess I have to find the logical number that will simply give me the position of the result letter...
I tend to play with the numbers 3 and 6 that keep coming back...

3 - (6/3) = 1
1 x (6x3) = 18
18 x (6/6) = 18 x (3/3) = 18
...
Not sure which pattern is missing. I get the "24 for X " idea but I guess I could also end up with 9 and therefore I as the candidate...

sirbountyCommented:
I saw that, but felt that 24 was a better candidate...I'll agree it's not rock-solid. :^)

Guy Hengel [angelIII / a3]Billing EngineerCommented:
tossing in an idea... consider the number of consonants and vowels ... so C=2 (B=1)
A=1
C=2
R=14

S = 15
X = 19
I = 3
Y = 20

1 2 14 14 ?

0
 
sirbountyCommented:
Not sure I follow that?
Number of consonants in c is 2?
0
 
Guy Hengel [angelIII / a3]Billing EngineerCommented:
B is the first consonant, as A is the first vowel...
again, was just an idea. considering it to be a universal logic, I guess can't be that, as some languages consider different classifications in regards to vowels and consonants ...
really brain-fucking ...

sirbountyCommented:
No, I hear ya - I just didn't understand it before.
Obviously that's a toughie, no doubt...so many different angles will help solve it.
I still like Carry - haha... :^)

I think a contest in French would be more likely to have C A R R Y
as an answer than a contest in English where it might be more obvious.

ozoCommented:
Although then why not C A R R S ?

Strange, I can't find carr in an online dictionary even though I know it means wet woodland.

DenisvtAuthor Commented:
Oh well, time up for me. Could not find the answer to number 2, there must be a logic between letters, although not linked to a particular language. Thanks to all those who helped !
