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

1.000.015

Back to our friend zero me thinks
Lost in ?????

Careful, the word "and" is only used when indicating a decimal point.

Nine hundred ninety nine thousand nine hundred ninety nine would either be:
1,000,049 (excluding spaces)
1,000,057 (including spaces)

I can see where you are coming from, but can you explain the solution again please?

Spoiler for It's like this ...

Add the letter-length to the value of the number.
For the 50th term you get f-i-f-t-y [5 letters] + 50 [value] = 55

[benkenobi]

The correct answers are 55, 73 and 110

How do you GET those answers?
Easy.

The first number in the series is 4
You get 4 by counting the letters in the number O-N-E and adding them to the value of the number.
Three letters in the word ONE plus the value of ONE = 3+1 = 4
The next number in the series is 5
T-W-O = 3 plus the value of 2 = 5
The next number is 8
T-H-R-E-E = 5 plus the value of 5 = 8
And so on, and so on, and so on

Really quite simple.

Fifty = 5+50 = 55
Sixty Three = 10+63 = 73
One Hundred = 10 + 100 = 110

AND when you write numbers into words on cheques/checks is it not?

[phil]

Spoiler for REAL EASY

You just take the number of letters in the written form of it added to the actual numerical value. 100 is 110
(o-n-e-h-u-n-d-r-e-d (10) +100)
50 is 55 and 63 is 73 (f-i-f-t-y(5)+50 and s-i-x-t-y-t-h-r-e-e (10)+50

wow I knew the answer just by looking at it for one minute somehow. I am amazed at myself.

How come no one used spoilers ( now that I look back at other people's answers)
?

AND when you write numbers into words on cheques/checks is it not?

Just because its how you write it on your checks does not mean its the correct way of writing out numbers. rhapsodize was right, and its a VERY common misconception because its taught to you at such a young age and doesn't leave you easily.

I'll leave this link here in case you wanna click it.

AND when you write numbers into words on cheques/checks is it not?

No. The only time you're supposed to use "AND" in writing a check is before the cents [Two-hundred fifty AND no/100 dollars]. Which is indicating the decimal point. Fortunately, the school I work/teach in teaches the students this, as well -- the only time you use "AND" is to indicate the decimal.

[Hawkeye]

The use of AND depends on whether you are using American English or English English.

American: One hundred ten
English: One hundred and ten

See http://en.wikipedia....nglish_numerals

By the way the number sequence in this puzzle is in OEIS. A095945

a(n) = n + number of letters in n
