1. Lesson 5. 2. 1 – How do you describe a sequence
Lesson – How do you describe a sequence? - Generating and Investigating Sequences
Objective - I will be able to identify a sequence as being Arithmetic, Geometric or neither.

2. Arithmetic Sequence: A sequence of numbers such that the difference between the consecutive terms is constant (the same amount). This common difference is represented with a value d. Ex; {-12, -10, -8, -6, -4, -2, 0, 2, 4, 6, 8, 10…} Equation to find any term of an Arithmetic Sequence – an = a1 + d(n-1) Where a1 is the first number in the sequence, d is the common difference and n is number of the term you wish to find the value of.

3. Geometric Sequence: a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio. This common ratio is represented with a value r.
Ex; {5, 10, 20, 40, 80, 160, 320, 640…}
Equation to find any term of a Geometric Sequence – an = a1rn-1
Where a1 is the first number in the sequence, r is the common ratio and n is number of the term you wish to find the value of.
