seems to be a geometric sequence which is found by [tex] a_{n}=a_{1}(r)^{n-1} [/tex]
an=nth term a1=first term r=common ratio
first term is 0.75 it doubles each time so common ratio is 2
[tex] a_{n}=0.75(2)^{n-1} [/tex] to find the nth term, input n and evaluate example to find the 20th term [tex] a_{50}=0.75(2)^{20-1} [/tex] [tex] a_{50}=0.75(2)^{19} [/tex] [tex] a_{50}=0.75(1048576) [/tex] [tex] a_{50}=786432 [/tex]
just to find the kth term, input k for n in [tex] a_{n}=a_{1}(r)^{n-1} [/tex]
