The sum of a series of integers (1,2,3.. n)is n(n+1)/2 so the mean is the total/n, hence n(n+1)/2n =6n/11 solve for n I got n=11. answered by Dr Russ. July 27, 2011. Thank you ... Web6 mei 2024 · Try to make pairs of numbers from the set. The first + the last; the second + the one before last. It means n-1 + 1; n-2 + 2. The result is always n. And since you are adding two numbers together, there are only (n-1)/2 pairs that can be made from (n-1) numbers. So it is like (N-1)/2 * N. Share Improve this answer Follow
Proving an infinite number of primes of the form 6n+1
Web6 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) WebWe can use following procedure: let y = ( 2 n + 3 n) 1 n. Then we can see that ln ( y) = ln ( 2 n + 3 n) n on the right side, limit is in the form infinity/infinity, so use L'hopitals rule, take derivatives, we would have 2 n ln ( 2) + 3 n ln ( 3) 2 n + 3 n charging a tesla at electrify america
