If you have ten fingers that means you have two more than most people (I have eight and two thumbs, personally...

15. Just to refresh your memory on that so called brick wall maths Q I set yesterday.

The two sequences of numbers I mentioned seem to obey the same general equation only with different starting point. A hint to answering this question is to consider the structure of triangle number.

Any given triangle number can be described by T= n(n+1)/2. For T to be a square number, either: 1, n is square and (n+1)/2 is square; or 2, n/2 is square, and (n+1) is square (or n = (n+1)/2, which solves to n = 1). This is really all you need to find these two sequences of number I mentioned before. But, the method my friend and I used to get there wasn't a pretty one. And we didn't know how to argue that we didn't actually miss out on anything.

Anyway, hope the hint will trigger a torrent of thoughts.

hehehe. believe me, had i any mathematical ability i would have taken it, probably even as a degree. it's the one blot in the story of my life; the inability to think mathematically. a very respectful course nonetheless, beaten only by medicine and maybe a science or two .

Are you sure that's a necessary condition for t to be a square?

16 is a square, but neither 8 or 2 are squares.

I'm missing something here lol.

That's why I said I probably missed out on something. From what I remember, the first few numbers in the sequeneces we found gave every number that fit the criteria without missing anything out.

I'll spend sometime on it and see what I can come up with.
