Sequences

Introduction
In this paper I will be defining the term graph sequence, recursion formulas and arithmetic
sequence. I will also solve the two problems given. Lastly, I will tell how the sums compare to
one another.
Definition
So what exactly is a graph sequence? A graph sequence is basically a set of discreet points on
a graph. So they are basically the points that we plot on a graph. The recursion formulas are the
nth number term of a sequence. It is the function of the term and can also define sequences using
the recursion formulas. The recursion formula looks something like this;
a
n
= 1/n
. The last
definition that I will cover is the arithmetic sequence. The arithmetic sequence is defined as a
sequence in which each term after the first differs from the preceding term by a constant amount.
An example of how the formula would look is;
a
n
=1n+d. N
is the number of the sequence such
as the number of months, years, etc.
