Recall first that (1 + 2 + 3 + ⋯ + n) = n(n + 1) 2 so we know 13 +23 +33 + ⋯ +n3 =(n(n + 1) 2)2. Listen. 1:27. Cie. de Saint-Gobain offered to buy CSR Ltd. for A$4.3 billion ($2.8 billion), the French building-materials producer said. The offer price of A$9 a share represents a 34% premium to Sum of Series (n^2-1^2) + 2(n^2-2^2) +.n(n^2-n^2) Finding n-th term of series 3, 13, 42, 108, 235… Sum of the natural numbers (up to N) whose modulo with K yield R Yes, If we remove $(1,2)$ or $(2,1)$ then it is anti-symmetric. The relation is transitive, we do not need $(2,3)$ and $(3,4)$ to be in the set. Especially there is no pairs in the relation $(2,x)$ and $(x,3)$, which is what we would need in order to force $(2,3)$ to be in the relation due to transitivity. 6. In example to get formula for 1 2 + 2 2 + 3 2 + + n 2 they express f ( n) as: f ( n) = a n 3 + b n 2 + c n + d. also known that f ( 0) = 0, f ( 1) = 1, f ( 2) = 5 and f ( 3) = 14. Then this values are inserted into function, we get system of equations solve them and get a,b,c,d coefficients and we get that. f ( n) = n 6 ( 2 n + 1) ( n + 1) So when you get to $1,2,2,3$ this can only go to $1,2,2,3,2,3,3,4$. In the statement of the problem we see $1,2,2,3$ but we don't see the next $4$ numbers, which are the solution.
