so each term is ound by subtracting 13 from the previous term
an aritmetic sequence can be written as
 were
 were 
 is the nth term
 is the nth term
 is the first term
 is the first term
d is common difference, which can also be found by doing 
n=wich term
we know that  and we can find d
 and we can find d
 ,
, 
so te general term is  which can also be expanded and written as
 which can also be expanded and written as
