How To Find The Nth Term Of A Cubic Sequence How to find the general

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:

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

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.

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.
