seems to be a geometric sequence which is found by
\(a_{n}=a_{1}(r)^{n-1}\)

an=nth term
a1=first term
r=common ratio

first term is 0.75
it doubles each time so common ratio is 2

\(a_{n}=0.75(2)^{n-1}\)
to find the nth term, input n and evaluate
example
to find the 20th term
\(a_{50}=0.75(2)^{20-1}\)
\(a_{50}=0.75(2)^{19}\)
\(a_{50}=0.75(1048576)\)
\(a_{50}=786432\)


just to find the kth term, input k for n in
\(a_{n}=a_{1}(r)^{n-1}\)
