Sum of n, n², or n³ Brilliant Math & Science Wiki
Answer (1 of 11) I have wondered how the closed form for the sum of squares for the first n natural numbers was derived Given the formula for the sum 1^2+2^2++n^2= n(n+1)(2n+1)/6 I learned to prove its correctness using mathematical induction.

Example 1 For all n ≥ 1 prove that 12 + 22 + 32 + 42 ++ n2 = (n(n+1)(2n+1))/6 Let P(n) 12 + 22 + 32 + 42 ++ n2 = (????(???? + 1)(2???? + 1))/6 Proving.
What is the value of 1^2+2^2+3^2+…n^2? Quora
Little ant said 1^2 + 2^2 + 3^2 + + 2^n = 2^ (n1) This makes absolutely no sense I mean look at it for a second firstly you failed to notice the pattern correctly since 2^n means 2^1+2^2+2^3 instead of what is shown And secondly how can that all equal 2^ (n1) when on the left side of the equation you already have 2^n which means User Interaction Count 11.

4^2 +…+ n^2 = (n(n+1 1^2 + 2^2 Prove by Induction: + 3^2 +
Explanation using the method of proof by induction this involves the following steps ∙ prove true for some value say n = 1 ∙ assume the result is true for n = k ∙ prove true for n = k + 1 n = 1 → LH S = 12 = 1 and RHS = 1 6 (1 + 1)(2 +1) = 1 ⇒result is true for n = 1.
