I need help with recursive form please someone explain this problem!!

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)

answer: i guess 105 degrees?
