moomoo,
finding the 'generalisation' means finding a formula to work out the number of matchsticks for any size pattern.
If you think of a formula as a meat mincer, then the input here (meat) is the number of the pattern, and the output (mince) is the number of matchsticks. So you only have to put in which number pattern it is, and the formula tells you how many matchsticks you will need.
Am I making sense?
..
So when you have your formula, you can just put in n=50 and it will churn out how many you need for the 50th picture in the sequence (which you won't need to draw).

He has explained it all to me and I think I nodded in the right places.
