    What Comes Next ?

    av_nefardec: Hmm. I had a(n+1) = (a(n) * (n+1) ) / (n * n) , and was taking a(1) = 2 (should it be 1/2?).

    So,

    a(1) = 2

    a(2) = (a(1) * (2+1)) / (2*2) = 6/4 = 3/2

    a(3) = (a(2) * (3+1)) / (3*3) = 12/18 = 2/3

    a(4) = (a(3) * (4+1)) / (4*4) = 10/48 = 5/24

    a(5) = (a(4) * (5+1)) / (5*5) = 30/600 = 1/20

    Does this fall over at a(6)? Or is it the reduction that's important (ie I should have 6/120 instead of 30/600)? I'm getting the impression I've gone incredibly wrong somewhere, but can't quite see it.

    Ah .. unless it's not defined as a series?

    a(n) = (n+1)/n! ?

    Here's one I like:

    a(0) = 0

    a(1) = 1

    a(2) = 2

    a(3) = 3

    a(4) = 4

    a(5) = 5

    a(6) = 6

    Hint 1: a(7) is not 7.

    Hint 2: a(10) = 604810

    Hint 3: a(x) is independent of a(x-1)

    Edit, couple more hints:

    Hint 4: It's all about multiplying together lots of stuff. Plus one addition.

    Hint 5: Multiplying any number by 0 gives 0. Obvious, but it's fairly crucial to obtaining the sequence.

    When You Travel, Do You Pack Too Much ?

    Nope, always too little. Pack too much and you have to either throw it away, or carry it everywhere. If you forget something you actually need, buy it. Added bonus is you can get away with just taking carry-on hand luggage, and avoid waiting for hours stood around a baggage carousel at Birmingham International freezing to death.

  7. Addiction 101

    in Introductions & Off-Topic Discussion

    My name is Rich, and I'm a nicotine addict.

    Why? I wish I knew. I'm 28, and for the last 10 years, I've smoked around 40 cigarettes a day. A good idea? Of course not.

    I don't think I'm stupid. I even think I'm quite bright. I can see that smoking has zero benefits. I know a spend a small fortune each year. I know the effect smoking has on my health, and I'm reminded every time I exercise : standing bent doubled up coughing up a lung isn't glamorous. I know I stink of smoke. I know, if I don't quit, smoking will kill me. And yet I don't stop.

    I don't think I've an "addictive personality", if you believe in them. I shop, but I'm not a shopaholic; I drink, but I'm not an alcoholic; and hey, I even gamble, but I certainly don't need to register with Gamblers Anonymous. It's just nicotine.

    Do I want to quit? Yes. Every day I say will be my last. I throw out all my lighters, cigarettes and ashtrays at the end of the day. Does it last? Never. By midday, I'll have a new lighter, more cigarettes. I'll fashion an ashtray out of whatever I have to hand.

    Am I really just that weak-willed? Or I am missing something? Please, someone tell me there's some light at the end of the tunnel. Failing that, just tell me there is at least an end to the tunnel.

  8. Childhood Accident

    LOL, funny topic. For me: falling backwards off a wall onto the concrete floor of the back yard. I was only about 4 or 5, it was one of my earliest memories. It wouldn't have been so bad, but I was going to see Playaway at the Wetherby Playhouse that night. Rest of my family still went; I got a Playaway annual signed by Brian Cant himself. Irreplacable.

    Also got run over by a car when I was 9 on way back from fish and chip shop. Got no signed souvenirs that time, sadly, but hey: with 3 months off school, who cares? :P

    (Sorry to revive old thread, just seen it ..)

    E-mail Format Preference

    Agree with Mark on this one - most emails I receive in html don't actually need to be so - I can work out italic/bold/underline intent from surrounding text, and I'm quite capable of copy-and-pasting web addresses into a browser if I need to ..

    Do I get my bonus points now? Only I'm hoping I'll get free flights to the South Pacific when I reach 100000, and I've only got around 99970 to go ..
