Question 8 Prove 1.2 + 2.22 + 3.23 + .. + n.2n = (n1) 2n+1 + 2
Which means $$(2n+2)! = (2n+2) \cdot (2n+1) \cdot (2n)!$$ So when dividing $(2n+2)!$ by $(2n)!$ only those first two factors of $(2n+2)!$ remain (in this case in the denominator). Share

2N, 2N+1, 2N+2 redundancy. N refers to the minimum number of resources (amount) required to operate an IT system. 2N simply means that there is twice the amount of required resources/capacity available in the system. For a simple example, let's consider a server in a data center that has ten servers with an additional ten servers that act as.

((2n-1)!)/((2n+1)!) = 1/((2n+1)(2n)) Remember that: n! =n(n-1)(n-2).1 And so (2n+1)! =(2n+1)(2n)(2n-1)(2n-2). 1.
Prove by mathematical induction that the sum of squares of positive integers is n(n+1)(2n+1)/6
Factor n^2-2n+1. n2 − 2n + 1 n 2 - 2 n + 1. Rewrite 1 1 as 12 1 2. n2 − 2n+12 n 2 - 2 n + 1 2. Check that the middle term is two times the product of the numbers being squared in the first term and third term. 2n = 2⋅n ⋅1 2 n = 2 ⋅ n ⋅ 1. Rewrite the polynomial. n2 − 2⋅n⋅1+12 n 2 - 2 ⋅ n ⋅ 1 + 1 2. Factor using the perfect.

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)
