55 (If I'm allowed to change the 26 to 21 so we have every second term in the Fibonacci sequence - 0,1,1,2,3,5,8,13,21,34,55,...)

That would have been such a good answer, as the Fibonacci sequence ties in with Lars von Triers Nymphomaniac, which is related to a question I set a short while back. It would also, if you look hard enough, tie into my previous question about Breaking Bad.

Also, it might have made it easier for me to set some clues. As it is I'll have to give it some thought and hopefully by tomorrow I'll have come up with something.

The Gutfright sequence, like Fibonacci's version, can be expressed as Xn=aXn-1^b+cXn-2^d+e (where b=/=0 and d=/=0)

In other words, to find the next number in the sequence you must take the last two numbers into account.

70 maybe.

70 is too low. The correct answer is somewhere between 99 and 999, and it's an odd number.

Some more numbers may be helpful, perhaps?

What number comes next?

0,1,3,8,26,?

I believe the Gutfright sequence is Xn=Xn-2[sup]2[/sup]+2Xn-1+1, for values of n>=2 (X=n for n=0,n1)

Thus:
3 = 0[sup]2[/sup]+2*1+1
8 = 1[sup]2[/sup]+2*3+1
26 = 3[sup]2[/sup]+2*8+1
117 = 8[sup]2[/sup]+2*26+1

The next number in the sequence is 117.

Well done, 117 is the correct answer.

To find the next number in the sequence, double the previous number, add it to the square of the number before that (if there is one) and then add one.

Its the definition of a letter. Certain Welsh sounds (like ll) while made of two English letters only count as one letter in Welsh. Ergo, 58 letters in English becomes 51 in Welsh.

Correct. The digraphs 'ch', dd', 'ff', 'ng', 'll', 'ph', 'rh', and 'ph' all require two characters to write/type, but are considered to be a single letter in Welsh. Gutfright was close, but named the languages the other way around.

The place is, of course, Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch.(I won't get into the issues of whether that's the official name or not.)

Right then.

In the UK we have one of the world's only commercial source of a man made material.

What is it, where is it and if man made, why can no one else make it?

It is not clear from the question whether it is the only source or one of the world's few sources.

HMS Ark Royal and DaleCoooper both have the right answer, it is indeed low background steel. However I shall award the question to HMS Ark Royal as he got the material, location and source.

Its a naval question - was there any chance of me not getting it?

Actually second answer. Possibly a Coronation.
