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 :

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).

In mathematics, we use the word sequence to refer to an ordered set of numbers, i.e., a set of numbers that "occur one after the other.''. For instance, the numbers 2, 4, 6, 8,., form a sequence. The order is important. 8.2: Infinite Series. This section introduces us to series and defined a few special types of series whose convergence.

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.

Cubic Sequences To find the n th term of a cubic sequence we will need to find the first, second and third differences. Similar to a quadratic sequence you then subtract an^3 from your original sequence, leaving you with a quadratic sequence, where you then follow the same steps as above to find the n th term. Example:

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 +โฏ+ 100 = 2100(101) = 210100, which implies our final answer is 5050. _\square .
