Question 1008774: Plese help dont understad how to resolve.
Thanks in advance
An={3, 3/4, 3/16, 3/64...}

Answer by fractalier(6550)   (Show Source): You can put this solution on YOUR website!
Notice the first term, a1, is 3.
Each succeeding term thereafter is one-fourth as great. That means your common ratio, r, is 1/4.
We can write this geometric sequence as
an = a1 * r^(n-1)
