WebΔ f ( n) = f ( n + 1) − f ( n) acting on polynomials f ( x) of degree d will result in polynomials in degree d − 1 (check this!) - the difference between f ( n) = 1 2 + 2 2 + ⋯ + n 2 and f ( n + 1) = 1 2 + ⋯ + ( n + 1) 2 is simply ( n + 1) 2, which is a quadratic in n, hence we should expect f to be cubic. WebCorrect option is C) Given that f(n+1)=2f(n)+1,n≥1 . Therefore, f(2)=2f(1)+1. Since f(1)=1, we have. f(2)=2f(1)+1=2(1)+1=3=2 2−1. Similarly f(3)=2f(2)+1=2(3)+1=7=2 3−1. and so …
