WebbAs we said before, the nth term rule of any quadratic sequence can be written in the form an2 + bn + c. So, lets substitute the numbers 1 to 5 for n to write out the first 5 terms of the sequence an2 + bn + c. If n = 1, an2 + bn + c = a + b + c If n = 2, an2 + bn + c = 4 a + 2 b + c If n = 3, an2 + bn + c = 9 a + 3 b + c Webbb=2,5 c=22 Jag skriver ekvationen: an=0,5n^2+2,5n+22 I facit står det något jag inte kan tyda. Det står att svaret är: 0,5n^2-0,5n Det enda jag vet att jag gjort annorlunda är att jag uttryckt formeln såhär an=an^2+bn+c (vilket de också sagt att man ska göra i infotexten innan denna uppgift dyker upp.

WebbAs pointed out in the previous section, the efficiency analysis framework con-centrates on the order of growth of an algorithm’s basic operation count as the principal indicator of the algorithm’s efficiency. To compare and rank such orders of growth, computer scientists use three notations: O (big oh), (big omega), and (big theta).
