    When you get patterns like this you may find it helpful to iqnore the fractions first.

    I find it helpful, especially when trying to write a function, to figure out what the 0th term would be. Like in this case, the function of n, the number of term, is: f(n)=1/32*4^n

    this is a goemetric sequence \[\frac{1}{8} (4)^{n-1}\]

    4 is the common ratio and 1/8 is the first term and n is the number of term
