ARTHMETIC AND GEOMETRIC SEQUENCES AND SERIES If a sequence follows a pattern of addition= ARITHMETIC SEQUENCE If a sequence follows a pattern of multiplication= GEOMETRIC SEQUENCE ARITHMETIC SEQUENCE - A list of numbers that follow a pattern of addition, - Ex. 4,7,10,13,16…. - Common difference (d)= the number that is added in order to create each term in the sequence. o To find d, subtract from each term that comes before it o In our example d= 3 - To find the n term of an arithmetic sequence use the equation - a na +1n-1)d a the nth term (the number in position n in the n= sequence) a 1=the first term in the sequence n= the position of the number in the sequence if the first time is not given to
