Wow, that's really tricky... even with the code, it took me several minutes to figure out:P

Help, I've been staring at this one for hours and still can't find the relationship between "N" and the "(Nth term) - N".

1 = 3
2 = 3
3 = 5
...
wait

one = 3
two = 3
three = 5
four = 4
....
fifty = 5
...
sixtythree = 10
...
onehundred = 10
...

1 3+1 = 4
2 3+2 = 5
3 5+3 = 8
...
50 5+50 = 55
63 63+10 = 73
100 10+100 = 110

The suggestion of subtracting N from the Nth term was a clue.
If you do it, you generate the third column in the following table.

Can you relate the numbers in the third column to N?
If you can, you've solved the puzzle.

```N   Nth term [Nth term]-N
=   ======== ============
1	   4		 3
2	   5		 3
3	   8		 5
4	   8		 4
5	   9		 4
6	   9		 3
7	  12		 5
8	  13		 5
9	  13		 4
10	 13		 3
11	 17		 6
12	 18		 6
--	 --		 -
49	 58		 9
50	 55		 5
51	 59		 8
--	 --		 -
62	 70		 8
63	 73		10
64	 73		 9
--	 --		 -
99	109		10
100   110		10
101   114		13```

Edit to remove spoiler for a day or two...

I got it, brill.
Spoiler for Don't ruin it. It's a good one, and easy to get to if you realise that it is a code.

The 50th term is 55.
Their difference is 5 = the number of letters in the word "fifty".

Is it possible that you have not gone further than 100 for a reason?
nine hundred and ninety nine thousand nine hundred and ninety nine.
What would you make of that using the same formula?
Spoiler for I make it

Ok i did some number crunching and realized the pattern is something like this
-2, +3, -1, +1, -3, +2, -(-1), +0, -(-4),etc Also it is like this...

-2, +3, -1, +1, -3, +2, -(-1), +0, -(-4),
I...........I..........I...........I..............I
+1 -2 +4 +3

I dont know what it means though...
