    The nth term of a geometric sequence is \[\large n _{th} \ term=ar ^{n-1}\] where a is the first term, r is the common ratio and n is the number of terms.

    We use geometric sequence because we have a common ratio, which is 4. If the difference had been the same, then we would have used arithmetic sequence. You can watch this video: http://www.virtualnerd.com/algebra-2/sequences-series/geometric/geometric-sequences/geometric-or-arithmetic-sequence
