[Question]

Here's what we had to do:

http://img85.imageshack.us/img85/7103/puzcopy3qk.png

There were 4 match sequences (see top right of image) and we had to find the formula for each the number of matches in the nth patern in each one. That was simple.

H being height, n being number in sequence.

Then we had all of the formulas and had to think of a formula to get the amount of matches in any sequence.

[Difficulty]

I managed to do that and get (2h+1)n+h but that was just by looking at it and couldn't really show any working out.

Could you advise me on what working out to show and then also prove it.

[Thoughts]

Well, I'm just a bit confused about showing working out and proving, and I currently don't have any ideas as to what to show.

Thank you for your time!
