chapter 13-1!!!!
this section was superr easy because it deals with patterns of different sets of numbers.
Arithmatic-you add to get the next term in an arithmatic sequence
Geometric-you multiply to get the next term in a geometic sequence
Examples: is this sequence arithmatic or geometric? 2,5,8,11
arithmatic, because you add 3 to each numberrr.
Examples: is this sequence arithmatic or geometric? 4,8,16,32
geometric, because you mulitply by 2 to each numberrr.
Examples: find the next to numbers in this arithmatic sequence; 4,7,10,13
16,19 <---answerrrrrr
Examples: find the next two numbers in this geometric sequence; 3,9,27
81,243 <---answerrrrr
