Quadratic Sequences: The Nth Term of a Quadratic …
WebA quadratic sequence has the general form T (n) = an2 + bn + c. Where a, b, and c are constants. For example, all of the following are quadratic sequences: 3, 6, 10, 15, 21,… 7, 17, 31, 49, 71,… 31, 30, 27, 22, 15,… Quadratic sequences are related to squared numbers because each sequence includes a squared number an 2. WebMar 13, 2014 · The formula for the n-th term is an = a0 + (a1 − a0)n + (a2 − 2a1 + a0)n(n − 1) 2 Using the results N − 1 ∑ n = 0n = N(N − 1) 2 and N − 1 ∑ n = 0n(n − 1) = N(N − 1)(N − 2) 3 leads to S = N − 1 ∑ n = 0an = a0N + (a1 − a0)N(N − 1) 2 + (a2 − 2a1 + a0)N(N − 1)(N − 2) 6 edited Mar 14, 2014 at 6:47 answered Mar 13, 2014 at 22:38 Jaume Oliver Lafont fifa 20 teams list
