Answer:
An=A1*2^(n-1)
Step-by-step explanation:
geometric sequence formula is
An=A1*r^(n-1), where r is the constant by which the terms are constantly getting multiplied,
lets find it: by dividing a term by its preceding term
(1/3)/(1/6)=1/3*6=6/3=2
Thus, the recursive formula for this geometric sequence is:
An=A1*2^(n-1)
