Graph of the terms u₁…uₙ of an arithmetic sequence (points in a straight line) or a geometric sequence (points on an exponential curve). Click a bar to see the term uₖ and the sum Sₖ computed from the formulas; the interest mode compares simple interest (arithmetic sequence) with compound interest (geometric sequence) period by period.
