They're not, but 2(n-1), 2n-1 and 2n are, so 3 divides one of them. by using a for loop I can find the last value of y, but i need to store all values of y from n =1 till n. Who do I do that, For example:The summation from i=1 to n of i = n(n+1) / 2 ==> Θ(n2). How do I derive $1 + 4 + 9 + \cdots + n^2 = \frac{n (n + 1) (2n + 1)} 6$, Proving $\sum_{k=1}^n{k^2}=\frac{n(n+1)(2n+1)}{6}$ without induction.

Le transport de marchandises par voie aerienne. It can be generalized to $$\begin{align}f(n, m) &= \sum_{k = 1}^n k^m \\&= \sum_{k = 1}^n \sum_{r = 1}^k k^{m-1} \\&= \sum_{1 \le r \le k \le n} k^{m-1} \\&= \sum_{r = 1}^n \sum_{k=r}^n k^{m-1} \\&= \sum_{r=1}^n f(n, m-1 ) - f(r - 1 , m - 1) \end{align}$$ to be able to recursively solve any case. ∴ P(k+1) is true when P(k) is true Learn Science with Notes and NCERT Solutions, Chapter 4 Class 11 Mathematical Induction. +2 votes. #• assume the result is true for n = k#.
