    A friend (going Christ but don't use UKL) and I spent about 40 mins on this problem during a maths lesson 3 months ago. We managed to get two sequences of numbers which generate numbers that fit the criteria of the quetions when put into a equation. But, unfortunately, I lost the sheet of paper to my beloved bin bag after the lesson. So, now, I'm just as clueless as you are, mate.
    It's difficult! Rather at a brick wall.

    Were your sequences recursive, or did they have like a general term? My brain much prefers the latter.

    There's a second-year historian whose nickname is Jesus. Does that count? I think his real name is Vittorio - not sure he knows about his nickname. He's friends with a beast of an Etonian called Henry. His nickname is Henry IX of Trinity College. Not sure which is less flattering.
    he's always early! he's never late! I like to call him Harry the Eighth!

    Yeah, I randomly tried r = 48 in your formula and pulled out a horrible decimal.

    The woman has to wait until her hormone levels are back in sync after child birth before starting up a regular menstral cycle again. It would also, I'd guess, be quite painful that soon after chidbirth!

    My reasoning is not sound (nor is it even reasoning at all!) but I think it's a more likely answer than the even number hypothesis beneath my last post.
    another point is that one baby could have been premature so making it easier to have another baby sooner

    my dad is only 11 months older than his sister... and neither were premature :rolleyes:

    no...my equation only works for certain values of r

    for r=2 it works, but not for r=4 (because it doesnt give a whole num), but for r=12, and r=70 and r=408 it works

    so in reality, i'm no closer than we were beofre....damn!

    It does tell you that there is AN eldest child though.

    I think pol's possibly got the right answer although the logic he used is definitely not entirely the same as my maths teacher's!
    even if you had twins one is older

    Well, one is born first, but they were conceived at the same time.

    well, if you have 2 kids conceived on the same day and one is born 2 months prematurely then that one is considered 2 months older apart from for developmental consideratiomns.. its the same thing.


    Anyway, if they were't monozygotic, one coud have been conceived slightly later
