SpletStep 1: Enter the terms of the sequence below. The Sequence Calculator finds the equation of the sequence and also allows you to view the next terms in the sequence. Arithmetic … SpletThe nth term rule of a quadratic sequence can always be written in the form an2 + bn + c. To find this rule, we need to find a, b and c. There are a couple of ways to do this, but in either case, we first need to find the first and second differences. We’ll start by finding the nth term rule of the quadratic sequence 6, 15, 28, 45, 66.

Splet16. nov. 2024 · First, we want to think about “graphing” a sequence. To graph the sequence {an} { a n } we plot the points (n,an) ( n, a n) as n n ranges over all possible values on a graph. For instance, let’s graph the sequence { n+1 n2 }∞ n=1 { n + 1 n 2 } n = 1 ∞. The first few points on the graph are, Splet14. feb. 2024 · S n = Σ (T n ) S n = Σ (n 2 )+Σ (n)+Σ (1) S n = (n (n+1) (2n+1))/6+n (n+1)/2+n.
