Determine whether the geometric series is convergent or Identifying Convergent or Divergent Geometric Series Step 1: Find the common ratio of the sequence if it is not given. I thought that the first one diverges because it doesn't satisfy the nth term test? So the first half would take t/2 to be walked, then we would cover half of the remaining distance in t/4, then t/8, etc If we now perform the infinite sum of the geometric series, we would find that: S = a = t/2 + t/4 + = t (1/2 + 1/4 + 1/8 + ) = t 1 = t. This is the mathematical proof that we can get from A to B in a finite amount of time (t in this case).
