Okay so obviously both are upright different, they can't be both right.... The ratio of the terms is (1/5) because 25/125 = 1/5 5/25 = 1/5 1/5 = 1/5 Since it's raised to the power of 'n', and our geometric sequence formula is: \[g_{n} = a_{1}*r^{n-1}\] We can modify it to be: \[g_{n} = a_{0}*r^{n}\] And the first term is 125, the ratio is 1/5, to go backwards, we multiply 125 * 5 = 625. \[f(n) = 625(\frac{1}{5})^n\]
