1)  An arithmetic sequence uses adding or subtraction
2)A geometric function uses multiplication or division

# data[].attributes.body
1) there are geometric and arithmetic equations
2) the sequences either diverge or converge

# data[].attributes.body
1. I remember that there are two types: Geometric and arithmetic
2. I remember that geometric has to do with multiplication and arithmetic has to do with addition. There are also specific equations for each type.

1. In order to find the difference in an arithmetic series, subtract one term by the previous term.

2. Arithmetic series never converge, but rather always diverge.

1.) There are 2 ways to find sums of geometric sequences
2.) There are geometric and arithmetic sequences

# data[].attributes.body
. 2 things I remember are:

1) Two types: geometric and arithmetic sequences. For arithmetic you have to find common difference and for geometric you have to find common ratio
2) There are equation for each that show how to find the sum, there are recursive and explicit formulas, one is used for adding/subtracting one is used for multiplying.

2 Things I Remember About Sequences and Series:

1. Arithmetic Series do not converge

2. Series are different from sequences in the sense that series relate to the sum of all of the parts of the series

1. The variables R and D differ depending on whether it is a geometric or arithmetic sequence.
2. When using the equation an=a1+d(n-1), you can find both the value of a term or what number that term is.

1. the number on the top of the sigma stands for how many terms are in the sequence
2. the sum of the terms of a sequence is called a series

1. Two types: Geometric and arithmetic
2. There is a recursive and explicit formula

- There are two types- geometric and arithmetic
- Arithmetic is used for adding and subtracting.

1) To find the sum of a series you use the formula, S infinity=g1/1-r.
2) S n=n/2(a1+an) is an important equation used for arithmetic sequences.

1. there a 2 types of sequences, one is geometric and has to do with dividing/multiplying, and the other is arithmetic, which is adding/subtracting
2. you can find the sum of every number in a geometric sequence by using the infinite equation

1) Sequences - there are two types : arithmetic and geometric

2) there are recursive and explicit formulas

1.) Arithmetic sequences are with either addition or subtraction, and geometric sequences are with multiplication and division.
2.)  There are two different ways to find the sum of a geometric sequence.

# data[].attributes.body
1.  Arithmetic deals with adding and subtracting, in terms of what you did with the common difference, and geometric deals with multiplying and dividing.
2. There is a recursive and explicit formula that is used when dealing with these types of problems.

1. a sequence is a function whose domain is the natural number set
2. a series is the sum of the terms of a sequence.

1.) There are two types: geometric and arithmetic.
2.) Sequences can either converge or diverge.

# data[].attributes.body
1. There are two types of sequences and series: Geometric and Arithmetic-able to analyze with equations needing the first term and the common difference.
2. I believe that to find the infinite sum, you need the geometric series first term and the common difference.

1. The common ratio is found by dividing a term by the previous one
2. Recursive sequences rely on using the previous terms to obtain the next ones
