In the sequence 1, 2, 4, .... an an , every nth term for n > 1 is created by the equation an=a(n?1)?2 an=a(n?1)?2 . by what percent is the 11th term greater than the 9th term in this sequence?
each term is doubled the equation is [tex]a_n=a_1(2)^{n-1}[/tex] where an=nth term a1=first term n=which term
ok
so if the 9th term is x then the 10th term is 2x then 11th is 4x so how much larger is the 11th term than the 9th term? 4x vs x it's 4 times bigger or 400%
