I've just finished deciding that the last question in my little sister's maths homework is impossible. Finding an nth term rule for the following:
2 9 17 27 39
Obviously, it was supposed to be:3 9 17 27 39
making it a simple n2+3n-1. Anyway, after half an hour of obsessively finding differences of differences of differences of differences I finally came to the conclusion that if 0 occurs anywhere but at the edges of a differences of differences(...) triangle, an nth term using powers of n is impossible.Now, the promised film review. I saw Grown Ups at the cinema tonight; true to form, Adam Sandler, Kevin James et al. guaranteed a laugh per minute. It was real easy-viewing stuff, recommended for anyone who just fancies a good laugh.
All of this, however, does not make up for the disappointing lack of post today. A whiteboard on Wednesday, a letter from Parliament on Thursday, yet nothing today.
