WebbSo T (n) = a* (n^2) + bn + c for some constants a, b, c. Now here's what I think. Let's assume that the body loop takes constant time 'a'. Then that itself will be looped over for a* (n^2) times. So, I don't understand from where b*n + c comes!

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 Webb3 dec. 2024 · The question tells us that (n + 2)! = n! (an² + bn + c) So, we can write: (n!) (n + 2) (n + 1) = n! (an² + bn + c) Divide both sides by n! to get: (n + 2) (n + 1) = an² + bn + c. Use FOIL to expand left side: n² + 3n + 2 = an² + bn + c. In other words: 1 n² + 3 n + 2 = a n² + b n + c. So, a = 1, b = 3 and c = 2. This means abc = (1) (3 ... black coffee video live
