The 700th term in a geometric sequence is 20. If the common ratio of the sequence is 0.25, what is the 699th term?

Each term in a geometric sequence is the previous term multiplied by the common ratio. Since the 700th term is the 699th term multiplied by 0.25, the 699th term is 20 ÷ 0.25 = 80, so the correct choice is 80.
