trying to write my english essay, note the "trying"
i just don't seem to be able to get myself to write it, and it being a "dianogstic essay" isn't helping. it adds to the "i don't really bother" factor. english teacher is evil enough though: "I'll grade it if you do badly."
instead, i spent like a few hours to find a general rule that allows you to get Tn=(n+3)(n+1), n=1,2,3,... from the pattern 8, 15, 24, 35, 48,...
