To continue the long division we subtract $(n + 2) - (n - {1\over 3n})$ which gives us the remainder $2 + {1\over 3n}$. $$1+2^{2}+3^{2}+\ldots +n^{2}=\frac{1}{3}\left( n^{3}+3n^{2}+3n+1\right) - \frac{1}{3}n-\frac{1}{2}(n^2+n
This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts.25 B. Fig ure 3 . Using principle of mathematical induction, prove that 4 n + 15 n − …
Best answer Suppose P (n) = 2 + 5 + 8 + 11 + … + (3n – 1) = 1/2 n (3n + 1) Now let us check for the n = 1, P (1): 2 = 1/2 × 1 × 4 : 2 = 2 P (n) is true for n = 1.
2. Differentiation. Simplify and combine like terms. Cite. Just pick a number, any number: If the number is even, cut it in half; if it's odd, triple it and add 1.

Do you mean, how do you prove that 2+5+8++(3n-1)=(3n^2+n) /2 for all positive integers n? That depends on what you have learned, and the goal of the proof. Tap for more steps 3n⋅n+3n⋅3+2n+2⋅3 3 n ⋅ n + 3 n ⋅ 3 + 2 n + 2 ⋅ 3.. 21 g. $ Share. P (k) = 2 + 5 + 8 + 11 + … + (3k – 1) = 1/2 k (3k + 1) … (i) Therefore,
induction, the given statement is true for every positive integer n. (d + 1)3 =d3 × (d + 1)3 d3 < 3d3 < 3 ×3d = 3d+1. Pembahasan soal rumus suku ke n nomor 1. Now to solve the problem ∑ n i=1 (3i + 1) = 4 + 7 + 10 + + (3n + 1) using the formula above:. 3N+1 Problem Algorithm. = n. an n = 3n n + −1 n a n n = 3 n n + - 1 n. In order to compute the next term, the program must take different actions depending on whether N is even or odd. answered May 18, 2015 at 12:41. Sum of 2nd and (n-1)th terms = 4 + (3n − 5) = 3n − 1.
