How To Find The Nth Term Of A Cubic Sequence How to find the general
Cubic Sequences (Difference Method for the nth n th term) Cubic sequences are characterized by the fact that the third difference between its terms is constant. For example, consider the sequence : 4, 14, 40, 88, 164,. 4, 14, 40, 88, 164,. looking at the first, second and third difference of this sequence would look like :

S n = 2n(n+1). Find the sum of the first 100 100 positive integers. Plugging n=100 n = 100 in our equation, 1+2+3+4+\dots + 100 = \frac {100 (101)} {2} = \frac {10100} {2}, 1+ 2+3+4 +⋯+ 100 = 2100(101) = 210100, which implies our final answer is 5050. _\square . Show that the sum of the first n n positive odd integers is n^2. n2.

The cubic formula is the closed-form solution for a cubic equation, i.e., the roots of a cubic polynomial . A general cubic equation is of the form (1) (the coefficient of may be taken as 1 without loss of generality by dividing the entire equation through by ).

A cubic number is a figurate number of the form with a positive integer. The first few are 1, 8, 27, 64, 125, 216, 343,. (OEIS A000578 ). The protagonist Christopher in the novel The Curious Incident of the Dog in the Night-Time recites the cubic numbers to calm himself and prevent himself from wanting to hit someone (Haddon 2003, p. 213).

Since the first differences are the same, this means that the rule is a linear polynomial, something of the form y = an + b. I will plug in the first couple of values from the sequence, and solve for the coefficients of the polynomial: 1 a + b = 5. 2 a + b = 7. This system solves as: So the formula is y = 2n + 3.

Introduction to Sequences What are sequences? A sequence is an ordered set of (usually) numbers Each number in a sequence is called a term The location of a term within a sequence is called its position The letter n is often used for (an unknown) position Subscript notation is used to talk about a particular term
